Question

If the angle of incidence is 30°, what will be the angle of reflection ?​

Answer 1

Answer:

THE ANGLE OF INCIDENCE IS 30° THEN ANGLE OF REFLECTION IS ALSO 30°

I HOPE IT'S HELP YOU AND HAVE A NICE DAY.

Answer 2

60 degrees

• The angle between the mirror and the incident ray is 30 degrees.
• The sum of the angle of incidence and this angle (30) makes a right angle.
• So, the angle of incidence is 90 - 30 = 60 degrees.
• As the angle of incidence and the angle of reflection are equal, both angles equal 60 degrees.
