Question

You are a scientist who is tasked with figuring out the identity of an unknown wave. The wave has a velocity of 16,000nm/s and a frequency of 20Hz. Use the formula below to calculate the wavelength of the unknown wave.
(+1pt. for the correct wavelength)

λ = v/f

Once you have found the wavelength, compare it to the electromagnetic spectrum below. Which of the three major ranges does this wave belong to? Your options are ultraviolet, visible light, or infrared. If the wave falls within the visible color range, tell me which color this wave is most likely to be.
(+1pt. for choosing the correct range.)

Answer 1

First, let's calculate the wavelength of the unknown wave:
λ = 16000nm/s / 20Hz
λ = 800nm

Therefore, the wavelength of the unknown wave is 800nm.

Comparing this wavelength to the electromagnetic spectrum, we can see that the 800nm wavelength falls within the visible light range. Specifically, this wavelength corresponds to the color red in the visible light spectrum.

So, the unknown wave most likely belongs to the visible light range and is most likely to be red.
