Question

Read the following and answer any four questions from 16(1) to 16)
16
When a beam of light encounters another transparent medium, a part of
light gets reflected back into the first medium
while the rest enters the other. The direction of propagation of on
obliquely incident (00<i<909) of light that enters the other medium,
changes at the interface of the two media. Figure shows the path of light
ray travelling from medium 1 of refractive index m, to medium 2 of
refractive index n2
161) State the law connecting the angles shown in figure with the given
refractive indices
1611) Name this phenomenon of light and the law it is obeying
16111) Is total internal reflection possible in this case by adjusting the
direction of incident ray? Why?
16iv) If n = n2, redraw the given diagram
16v) Draw the path of light if the light travelling from medium 1 (air) fall
obliquely on the surface of a calm pond (medium 2)​

Answer:

16

When a beam of light encounters another transparent medium, a part of

light gets reflected back into the first medium

while the rest enters the other. The direction of propagation of on

obliquely incident (00<i<909) of light that enters the other medium,

changes at the interface of the two media. Figure shows the path of light

ray travelling from medium 1 of refractive index m, to medium 2 of

refractive index n2

161) State the law connecting the angles shown in figure with the given

refractive indices

1611) Name this phenomenon of light and the law it is obeying

16111) Is total internal reflection possible in this case by adjusting the

direction of incident ray? Why?

16iv) If n = n2, redraw the given diagram

16v) Draw the path of light if the light travelling from medium 1 (air) fall

obliquely on the surface of a calm pond (medium 2)

Answer 2

Answer:

haha you remember me... hm

I am fine

what about you?

will you be my friend??
