I need help on this portfolio project, I have to do a lab report on light refraction. The research question is "How does change in medium affect light?" and I need to make a hypothesis, but I don't know what to put.

Light travels with different speeds in different materials. It travels at 3E8 m/s in a vacuum but slower in air and slower still in glass. Because it travels with different speeds it is refracted when moving from one medium to another.
I think you can get at least two hypotheses from this information.

I need help as well it is the same question

3. sasha

I need help with the same question

4. Alison

Well this will help ok. I had the same answer when I was younger and I get it ok so here is the real answer. It is slow in air but slower in glass. Hopefully that helped a little. Bye I hope you do well believe in yourself ok. Have a great day.!!!!!!!!!
