Measure the angle of incidence `theta_1` and the angle of reflection `theta_2`. Try to see if they are related in any way.

Answer the following questions: Adjust the angles of the two tubes till you can hear the sound very clearly. Measure the angle of incidence theta1 and the angle of reflection theta2 . Give your opinion

Complete the analogy : Angle of incidence : 60⁰ :: Angle of reflection : ………….

Choose the correct alternative : The angle of incidence is ………… angle of reflection .

Fill in the blanks : The angle of reflection is ……….. To the angle of incidence .

For an angle of incidence theta on an equilateral prism of refractive index sqrt(3) , the ray refracted is parallel to the base inside the prism. The value of theta is

If A is angle of prism, delta is angle of deviation, i is angle of incidence and e angle of emergence,then what is the correct relation between them ?

A ray of light falls on a glass plate of refractive index mu=1.5 . What is the angle of incidence of the ray if the angle between the reflected and refracted rays is 90^@ ?

A plane mirror reflecting a ray of incident light is rotated through an angle q about an axis through the point of incidence in the plane of the mirror perpendicular to the plane of incidence, then (1) The reflected ray rotates through an angle 2q (2) The incident ray is fixed (3) The reflected ray does not rotate (4) The reflected ray rotates through an angle q

Glancing angle theta is equal to (where, I is angle of incidence and r is angle of refraction )

The critical angle between a given transparent medium and air is denoted by c. A ray of light in air enters this transparent medium at an angle of incidence equal to polarising angle theta_P . Deduce a relation for the angle of refraction in terms of c.
