Question

Calculate the value of angle of incidence.

Give with the formula

And please give it fast. ​

Answer 1

Answer:

the angle of incidence is equal to the reflected angle thrugh the law of reflection.the angle of incidence and angle of reflection is same. thas what i know

Answer 2

• For better understanding refer to the attachment above :

___________________________

Given :

• $\sf \angle SRY \:=\:55°$

To Find :

• $\sf Angle \:of \:Incidence$

Solution :

• We know that the normal makes angle of 90° with the surface .
• To find angle of incidence we need to subtract $\angle$ SRY from 90°

$\leadsto \sf Angle \:of\:incidence\:=\:90°\:-\: \angle SRY$

$\leadsto \sf Angle\:of\:incidence\:=\:90°\:-\:55°$

$\leadsto \sf Angle\:of\:incidence\:=\:35°$

• Angle of incidence = 35°

More Information :

• Two laws of reflection :

1. The angle of incidence is equal to the angle of reflection .
2. The incident ray , reflected ray and the normal at the point of incidence all lie on the same plane .
