What is the angle of refraction when a ray of light passes from ethanol to air if the incident angle is 34°? the refractive index of ethanol is 1.36 and of air is 1.00.

a.21
b.34
c.49
d.66

This problem can be solved using Snell's law: " n1 * sin theta1 = n2 * sin theta2"

Given:

n1 = 1.36
theta1 = 34 degrees

n2 = 1.00
theta2 = ?

1.36 * sin(34) = 1 * sin (theta2)
angle of refraction = 49.51 degrees

Among the choices, the correct answer is C.

Ifound this on google “two vectors are equal if they have the same magnitude and direction. they are parallel if they have the same or opposite direction. we can combine vectors by adding them, the sum of two vectors is called the resultant.” i hope this you.
