Question

Which of the following has the greatest frequency?

1) Violet light (410 nm)
2) Infrared light (850 nm)
3) Yellow light (610 nm)
4) All have the same frequency
5) Red light (690 nm)

Answer 1

Between yellow light of 610 nm and red light of 690 nm, yellow light has the greatest frequency because it has a shorter wavelength.

Step-by-step explanation:

The question pertains to the comparison of frequencies of different colors of light, specifically yellow light with a wavelength of 610 nm and red light with a wavelength of 690 nm. Using the relationship between wavelength and frequency (ν = c/λ, where ν is frequency, c is the speed of light, and λ is wavelength), we can determine that light with a shorter wavelength will have a higher frequency because the speed of light is a constant value.

The frequency of yellow light (610 nm) is greater than that of red light (690 nm). This is because yellow light has a shorter wavelength than red light, and as per the electromagnetic spectrum, shorter wavelengths correspond to higher frequencies. Therefore, the yellow light at 610 nm has the highest frequency compared to red light at 690 nm within the scenario presented.
