Name two important differences between light waves and sound waves

What is the equation that represents the law of reflection?

What is the difference between Fresnel diffraction and Fraunhoffer diffraction?

1. Light is electromagnetic waves while sound is mechanical.

Light wave is transverse and sound is longitudinal.

Explanation:

2.

<i = <r

3.

when distance between source and obstacle and distance between obstacle and screen is finite then the diffraction is fresnal diffraction

when distance between source and obstacle and distance between obstacle and screen is infinite then the diffraction is Fraunhofer's diffraction

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
