For a given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is.............. .
A ray of light makes an angle of 50° with the surface S1 of the glass slab. Its angle of incidence will be............... .
The process of separation of light into its component colour while it is passing through a medium is called
For the refraction of light through a glass slab angle of incidence is .............. angle of emergence.
Coin placed at the bottom of vessel when viewed from sides becomes visible only after filling water upto certain height. This is due to phenomenon of ........ .
When a ray of light enters a rarer medium from a denser medium, it gets partially reflected i.e. part of the light gets reflected and comes back into the denser medium obeying the laws of reflection. This is called .................. reflection.
Dispersion of light and mirage are two examples of the phenomenon where ............ takes place.
............. is formed as the combined effect of the refraction, dispersion, and internal reflection
During refraction of light through the glass slab refraction of light takes place ........... in a glass slab.
When a ray of light enters a rarer medium from a denser medium, for a particular value of i for which, the value of r becomes equal to 90°, is called the ..............angle.
Choose the correct statement regarding the incident ray, refracted ray and normal drawn at the point of incidence.
If the first medium is vacuum then the refractive index of medium 2 is called .............. .
