3. v.) The referactive indese of a medium with
respect to air is uz.
the angle of incid
of a ray of lig
light hour,
Calculate
angle of deletion of
of refraction,
the angle
that
ray in case​

Answer 1

Explanation:

Given, μ=

2

1

w.r.t. air i=45

∘

,r=?

Also, μ=

sinr

sini

⇒

=

sinr

sin45

∘

⇒

1

=

sinr

1/

2

⇒sinr=1

⇒r=90

Note that the ray is incident from denser medium and is refracted into a rarer medium air.
