Please draw sketches to understand the problem better.

10. A ray of light is incident on a liquid to glass interface at an angle of 35 degrees. Indices of refraction for the liquid and glass are respectively 1.63 and 1.52. What is the angle of refraction for the ray moving through the glass?

11. A 9.0-V battery moves 20mc of charge through a circuit running from its positive terminal to its negative terminal. How much energy was delivered to the circuit?

12. A woman looking in a makeup mirror sees her face at twice its actual size and right-side up. if she is 28.0 cm from the mirror what is its focal length?

13. What is the surface temperature of a distant star (which emits light as if it were a blackbody) where the ear wavelength is 480 nm? (at 35 degree, 94 wl, 10^-3)

Explanation / Answer

10) Given:

Given theta 1 = 35

n1 = 1.63
and
n2 = 1.52
we have to find
theta 2 = ?
Applying Snell's law the formula is as below-

n1 * sin(theta1) = n2 * sin(theta 2)

1.63 * sin(35) = 1.52 * sin(theta 2)

So,angle of refraction theta 2 = 37.95
