Question

Find the angle of incidence and angle of reflection from the diagram.

a. 450 , 400

b. 550
, 550

c. 600
, 600

d. 300
, 300​

Answer 1

angle of incidence = 90°-35° = 55°

we know that angle of incidence= angle of reflection

therefore angle of reflection will be 55°

$....$

Answer 2

Answer:

HEY MATE:-

Explanation:

==> angle of incidence = 90° - 35° =55°

TIPS TO SOLVE THESE TYPE OF QUESTIONS EASILY:--

a) YOU MUST KNOW ALL THE LAWS FOR REFLECTION TO SOLVE QUESTIONS EASILY.

b) PRECISE CALCULATION IS MUST.

c) YOU NEED TO KNOW SOME SPECIAL FEATURES OF NORMAL RAYS TO FIND ANGLES EASILY.

1) NORMAL IS PERPENDICULAR TO THE SURFACE OF REFLECTION.

2) NORMAL DIVIDES INCIDENT RAY & REFLECTED RAY IN EQUAL ANGLES.
