Question

26.The angle of incidence for which angle of incidence is 2times of the glancing angle *
90°.
60°.
45°.
70°. ​

Answer 1

Answer:

Glancing angle of incidence =50

0

.

So, angle of incidence i=90

0

−50

0

=40

0

And, angle of reflection, r=40

0

Angle between incident and reflected rays =i+r=40

0

+40

0

=80
