State and explain the laws of reflection of light at a plane surface (like a plane mirror), With the help of a labelled ray-diagram. Mark the angles of 'incidence' and 'reflection' clearly on the diagram. If the angle of reflection is 47.5°, what will be the angle of incidence?
Explain why, though both a plane mirror and a sheet of paper reflect light but we can see the image of our face in a plane mirror but not in a sheet of paper.
If a ray of light goes form a denser medium to a rarer medium, will it bend towards the normal or away from the normal?
Fill in the following blank with suitable word:
Light bends when is passes from water into air. We say that it is ............
Numerical problems.
The speed of light in water is 2.25 × 108 ms–1. If the speed of light in vacuum is 3 × 108 ms–1, calculate the refractive index of water.
The refractive index of a transparent medium is always greater than ______.
A pencil when dipped in water in a glass tumbler appears to be bent at the interface of air and water. Will the pencil appear to be bent to the same extent, if instead of water we use liquids like, kerosene or turpentine. Support your answer with reason.
When a ray of light travels normal to the given surface, then the angle of refraction is ______.
According to the second law of refraction, for a given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction:
In the formula for absolute refractive index \[n = \frac{c}{v}\], the quantity c represents:
