A sound wave strikes a mirror at an angle of 3o Calculate the angle between the incident ray andthe refiected ray(21 |
|
Answer» The answer will beθ=0° It is because, the angle of incidence is the angle between the normal and the angle at which the light/sound wave is incident on the surface. So, as the question says that the sound wave is incident perpendicularly on the reflecting surface then there the angle of incidence will be zero degree. |
