The diagram given below in fig shows a ray of light AO falling on a surface separating two media. Draw the refracted ray in each, case.
Write true or false
The angle formed between the normal and the refracted ray is known as the angle of incidence.
At the point of incidence, a line drawn at right angles to the surface, separating the two media, is called the normal.
The focal length of a convex mirror is equal to its radius of curvature.
Light travels in the same straight line path while passing through different media.
Fill in the blank
A .............. mirror is obtained on silvering the outer surface of a part of a hollow glass sphere.
