Ordinarily, sunlight is broken down into three major components: (1) visible light, with wavelengths between 0.4 and 0.8 micrometre, (2) ultraviolet light, with wavelengths shorter than 0.4 micrometre, and (3) infrared radiation, with wavelengths longer than 0.8 micrometre.

Examples Of Radiation

• Radio waves.
• Microwaves.
• Visible light.
• Infrared light.
• Light from the sun.
• Lasers.

Gamma rays have the shortest wavelengths of the electromagnetic spectrum, and the highest energies.

Infrared radiation has the longest wavelength. Ultraviolet radiation has the shortest wavelength.

When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.

The visible spectrum of light has frequencies ranging from 400−790THz. We can see that the colour Orange has the lowest frequency among the choices given. Hence the correct is option (C).

Color is the frequency of visible light, and it ranges from 430 trillion Hertz (which is red) to 750 trillion Hertz (which is violet). Waves can also go beyond and below those frequencies, but they’re not visible to the human eye.

They are: red, orange, yellow, green, blue, and violet….red green blue.
