Dispersion of light and mirage are two examples of the phenomenon where ............ takes place.
Light changes its direction when going from one transparent medium to another transparent medium. This is called ............ .
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 ........ .
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.............. .
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.
............. is formed as the combined effect of the refraction, dispersion, and internal reflection
Choose the correct statement regarding the incident ray, refracted ray and normal drawn at the point of incidence.
For the refraction of light through a glass slab angle of incidence is .............. angle of emergence.
During refraction of light through the glass slab refraction of light takes place ........... in a glass slab.
The process of separation of light into its component colour while it is passing through a medium is called
