When light moves from one medium to another, it is refracted. If it moves from a medium with refractive index n1 to one with refractive index n2, with an incidence angle to the surface normal of θ1, the refraction angle θ2 can be calculated from Snell's law.
The Snell's law states that the ratio of the sines of the angles of incidence and refraction of a wave (in this case beam/light) are constant when it passes between two given media.

Given that a <span>laser travels from glass to water at an angle of 35° with the normal, </span>

<span>. If water has an index of refraction of 1.33 and glass has an index of refraction of 1.52, then we have:

I think the answer should be A n goodluck
Answer:
27
Step-by-step explanation:
4 times 4 is 16
2 boxes in the middle
4 tiny boxes in each one in the middle
1 entire one on the outside
1+4+4+2+16= 27
You would have to do 500x 4 which is 2000
Answer:
A, 95.
Step-by-step explanation:
The answer is 95 because the square is at a curve at the bottom right, so you need to subtract that amount from the original area, which is 100. So the actual answer is 95, hope this helped!
