Visible light has frequencies ranging from 4*1014 Hz to 8*1014 Hz (400 THz to 800 THz) and wavelengths from 3.8*10-7 m to 7.5*10-7 m (380 nm to 750 nm). Red light has the lowest frequency (longest wavelength) and violet light has the highest frequency (shortest wavelength) of visible light.
Similarly, what is the frequency of infrared waves in Hertz?
Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Below infrared is the microwave portion of the electromagnetic spectrum.
What is the frequency of microwaves in Hz?
Electromagnetic spectrum | ||
---|---|---|
Name | Wavelength | Frequency (Hz) |
Infrared | 750 nm – 1 mm | 400 THz – 300 GHz |
Microwave | 1 mm – 1 m | 300 GHz – 300 MHz |
Radio | 1 mm – 100 km | 300 GHz – 3 kHz |

What color of light has the lowest frequency?
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.

What is the frequency of blue light?
The colors of the visible light spectrum
Color | Wavelength interval | Frequency interval |

Green | ~ 560–520 nm | ~ 540–580 THz |
Cyan | ~ 520–490 nm | ~ 580–610 THz |
Blue | ~ 490–450 nm | ~ 610–670 THz |
Violet or Purple | ~ 450–400 nm | ~ 670–750 THz |

What is the frequency of a light wave?
The frequency is the number of waves that pass a point in space during any time interval, usually one second. We measure it in units of cycles (waves) per second, or hertz. The frequency of visible light is referred to as color, and ranges from 430 trillion hertz, seen as red, to 750 trillion hertz, seen as violet.

How do I calculate the frequency of a wavelength?
Method 1 Frequency from Wavelength
- Learn the formula. The formula for frequency, when given wavelength and the velocity of the wave, is written as: f = V / λ
- Convert the wavelength into meters, if necessary.
- Divide the velocity by the wavelength.
- Write your answer.

Which Ray has highest frequency?
types of electromagnetic radiation highest frequency to lowest
- Gamma rays. these have the most frequency but have the lowest wavelength.
- X rays. have the 2nd highest frequency.
- Ultraviolet light. has the 3rd highest frequency.
- Visible light. has the 4th lowest frequency.
- infared radiation. has the 5th lowest frequency.
- microwaves. has the 6th lowest frequency.
- radio waves.

Which color of light has the most energy?
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
7
What is the frequency of ultraviolet light?
Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 × 1014 to 3 × 1016 cycles per second, or hertz (Hz), and wavelengths of about 380 nanometers (1.5 × 10−5 inches) to about 10 nm (4 × 10−7 inches).

What is the frequency of a wavelength?
Definition: Wavelength and frequency. Light is measured by its wavelength (in nanometers) or frequency (in Hertz). equals the distance between two successive wave crests or troughs. equals the number of waves that passes a given point per second.
9
What is the relationship between frequency and wavelength?
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
10
What has the highest frequency?
Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have highest frequencies and shortest wavelengths. The wavelengths vary across the electromagnetic spectrum from about 10–15 m to more than 104 m.
11
What is the frequency of the sound?
It is only useful or meaningful for musical sounds, where there is a strongly regular waveform. Frequency is measured as the number of wave cycles that occur in one second. The unit of frequency measurement is Hertz (Hz for short). A frequency of 1 Hz means one wave cycle per second.
12
How does the frequency affect sound?
An explanation of sound waves. The pitch of a sound is dictated by the frequency of the sound wave, while the loudness is dictated by the amplitude. When a drum is beaten, the air particles around the drum skin vibrate in the form of a compression wave.
13
Do all electromagnetic waves travel at the speed of light?
Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.
14
Which Ray has highest wavelength?
The Electromagnetic Spectrum consists of radio waves, microwaves (a type of radio wave), infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. Waves with the longest wavelengths have the lowest frequencies. Waves with the shortest wavelengths have the highest frequencies.
15
What are the three primary colors of light?
The primary colors of pigment (also known as subtractive primaries) are used when producing colors from reflected light; for example, when mixing paint or using a color printer. The primary colors of pigment are magenta, yellow, and cyan (commonly simplified as red, yellow, and blue).
16
Which color has the highest wavelength?
The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum.
17
What are the invisible wavelengths?
All colors of light are made up of electromagnetic radiation and it travels in waves, some of which are visible to the human eye. Many color waves, however, are invisible to the human eye. Visible light wavelengths run from 400 nanometers for violet light to 700 nanometers which is represented by red light.
18
What color of light has the longest wavelength?
The visible colors from shortest to longest wavelength are: Violet, Blue, Green, Yellow, Orange, and Red. Infrared Radiation has a longer wavelength than visible Red light. Ultraviolet Radiation has a shorter wavelength than the visible Violet light.
