Explanation:
Below is an attachment containing the solution.
Answer:
White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.
The functions of angles are used to find unknown lengths or angles that can't be measured, in terms of known quantities. The trig functions of angles are ratios of lengths, so they're bare naked numbers without units.

sorry this is by accident, but i can't delete it
Answer:
wavelength is equivalent to the velocity divided by the frequency
