is the angle of refraction equal to the incident ray like in this problem always the case or is it only if it is in the same medium?

[derekowens]

@InvaderZim931 Only if it is the same medium, and only if the sides are parallel as in this case.

You don't have to do baby steps lol. Just solve for 'r' right away.

[derekowens]

@joejacksonriley Agreed! My course, though, doesn't assume that the students are algebra experts, so for many of my students it is helpful to show the steps in detail. If you can solve for r in your head, though, that's great.

why every Examples has someone talking about Air is 1.0003

while 11.2.3a said "we will round it to 1"...

[derekowens]

@Opapaappa If the light is refracting from air into some other substance, such as water or glass, then the .0003 is not significant. If it is refracting from air into space (or space into air), then it would matter.

thank you!!!!!!! this helps so much and I won't be screwed for my physics test tomorrow!!!
