Laws of Refraction:
There are two laws of refraction.
The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plane.
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from single medium to another medium. This constant is known as refractive index.
A wave is a disturbance which transmits power and momentum from one place to the other without the transport of matter.
The impression of sound heard by our ears persist in our mind for 1/10th of a second. If another sound is heard before 1/10 second is over, the impression of the two sound mixes up
When a string under tension is set into vibration, transverse harmonic rays propagate along its length. When the size of string is same, reflected rays will also exist. The operati
