Question

the angle of incidence is always __to angle of reflection​

Answer 1

Answer:

The ange of incidence is always equal to the angle reflection.

More:

• When a plane mirror is tilted to an angle θ, the reflected ray rotates through 2θ.
• In case of normal incidence, the reflected ray of light retraces its path. Angle of deviation is 180° there.
• When two mirrors are kept at an angle θ, a ray of light falling to one them suffers net deviation of (360° - 2θ).
• In case of no. of image formation:

1. (360°/θ) is even, then no. of images formed = 360°/θ - 1.
2. (360°/θ) is odd, and the obj. is kept symmetrically then no. of images formed = 360°/θ - 1.
3. (360°/θ) is even, then no. of images formed = 360°/θ if obj. is not placed symmetrically.

• Normal makes a right angle with the plane.

Answer 2

Answer:

The angle of incidence is always equal to angle of reflection.
