Question

In partial reflection and refraction of light from surface of glass slab, if angle of
incidence angle i= 43º and angle of refraction angle r= 25°, then the reflected ray and
refracted ray are deviated from the incident ray by and respectively.​

Answer 1

From law of reflection, r1=i

From Snell's law,

sini=μsinr2

=μsin(90∘−r1)

=μcosr1=μcosi

Answer 2

Answer:

94 and 18

Explanation:

94 and 18 ..three bulbs of 100w each
