Question

Class-
1) The return of light into the
same medium after striking a
surface is called.
2) The incident ray, reflected ray,
normal at the point of incidence
all lie in the........... Plane
3) The angle made by the
incident ray with the mirror is
known as..
4) The formula for glancing
angle is....
5) Angle of incidence is 10° then
the angle of reflection is....
6) The angle of incidence is 60
º then the angle of deviation
is.......
7) If the angle of reflection is 30 °
then the glancing angle is....
8) If the angle of incidence is
pº, then the angle of deviation is​

Answer 1

Answer:

1.reflection

2.same

3.angle of in incedence

4.

5. 10

6. angle of incidence -angle of reflection

7.60

8

Answer 2

Answer:

hey mate,

1) reflection

2) same

3) angle of incidence

4) Glancing Angle (θ)

nλ = 2d.sin⁡θ

5) 10°( <i = < r )

6) 30°

7) angle of reflection + glancing angle of incidence = 90

90 - 30 = 60°

8) d = 2( 90 - <i )

Explanation:

Glancing angle of incidence is defined as the angle between the incident ray and the reflecting surface.

hope this would help you!!
