I know student 2 is right but don't know how to explain it Three students are arguing about what happens when light travels from water into air. Their claims are in bold. Two of the claims are incorrect. Think about which claim you support and why.

Student 1: “When a light wave travels from water to air, it speeds up from 200,000,000 m/s in water to 299,700,000 m/s in air. That is a big increase in speed. There must be a change in frequency and wavelength for that to happen. If speed increases, then wavelength and frequency also increase.

Student 2: I disagree. The simulation and an article showed that only one of the variables changed, but i don't remember if it's frequency or wavelength that change. When speed increases, then only one of the variables change.

Student 3: I disagree with both of you. When light travels from water to air, it doesn't speed up. Where would it get the energy for that? The speed of light stays the same when travelling to different media, if the wavelength increases then the frequency decreases. It's the same reason that radio waves and x-rays travel in space at the same speed.

Use mathematical reasoning to support a claim. Credit will only be given to work done on paper. You may upload your work here or email it to your teacher.
