Light in air enter crown glass (n = 1.52) at an angle of 35 degrees. What is the refracted angle?

Dovator [93]

Answer:

22.17 degree

Explanation:

n = 1.52

Angle of incidence, i = 35 degree

Let the angle of refraction is r.

use the Snell's law

n = Sin i / Sin r

Sin r = Sin i / n = Sin 35 / 1 .52

Sin r = 0.37735

r = 22.17 degree

Thus, the ray is refracted at an angle of 22.17 degree.

You are walking down a straight path in a park and notice there is another person walking some distance ahead of you. The distan

Setler79 [48]

Answer:

25.52 m

Explanation:

Relative speed between the person and I would be the difference of our speeds

$v_r=2.85-1.09=1.76\ m/s$

Time taken by me to walk up to the person = 14.5 s

Distance is given by

$Distance=Speed\times Time\\\Rightarrow s=vt\\\Rightarrow s=1.76\times 14.5\\\Rightarrow s=25.52\ m$

The person was 25.52 m ahead of me when I started running
