Aray of light strikes a flat block of glass (n = 1.52) of thickness 1.50 cm at an angle of 36.0° with the normal. trace the light beam through the glass, and find the angles of incidence and refraction at each surface. if the angle of incidence at first surface is 36.0° (all angles are measured from the normal), determine the following angles. angle of refraction at first surface

angle of refraction at first surface is 22.74°

Step-by-step explanation:

Given data

thickness = 1.50 cm

n = 1.52

angle = 36.0°

to find out

angle of refraction at first surface

solution

we will apply here  Snells law that is

n1 sinθ1 = n2 sinθ2

θ2 = sin^-1 ( n1/n2) sin θ1

here n1 is 1 and n2 is 1.52 and θ1 = 36.0°

θ2 = sin^-1 ( n1/n2) sin θ1

θ2 = sin^-1 ( 1 / 1.52 ) sin36

θ2 = 22.74°

angle of refraction at first surface is 22.74°

i can you with this sweetie!

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
