When a ray of light travelling in glass enters into water obliquely : (a) it is refracted towards the normal (b) it is not refracted at all (c) it goes along the normal (d) it is refracted away from the normal
A ray of light travelling in water falls at right angles to the boundary of a parallel-sided glass block. The ray of light : (a) is refracted towards the normal (b) is refracted away from the normal (c) does not get refracted (d) is reflected along the same path.
Light travelling from a denser medium. to a rarer medium alone a normal to the boundary : (a) is refracted towards the normal (b) is refracted away from the normal (c) goes along the boundary (d) is not refracted
As light rays pass from water into glass, are they refracted towards the normal or away from the normal?
