If a wave is incident on a hard surface 1 at an angle of 30o as shown in the above diagram, find
i. the angle of reflection on hard surface 1
ii. the glancing angle on hard surface 1
iii. the angle between the incident wave and reflected wave on hard surface 1
iv. the angle of deviation of the wave on hard surface 1.
v. the angle of reflection on hard surface
vi. the angle of incidence on hard surface 2
vii. the angle of reflection on hard surface 2
viii. the glancing angle on hard surface 2
ix. the angle between the incident wave and reflected wave on hard surface 2
x. the angle of deviation of the wave on hard surface 2
xi. the total angle of deviation of the wave from beginning to the end. .
