Question

Suppose you are an astronomer, and a child asks you to explain the light given off by stars. In your own words, describe the relationship between the energy, frequency, and wavelength. Be sure to include information about the electromagnetic spectrum in your discussion. (5 points) >

Answer 1

There are different kinds of light, and they vary by energy, frequency, and wavelength. Energy and frequency go together, so the light that has high frequency has high energy, and vice versa. Frequency and wavelength are opposites, so as frequency increases, wavelength decreases. The light that we see from stars is visible light, which is only a very small part of the different possible kinds of lights. Our eyes are only able to see within a small range of wavelengths.
