Basics of diffraction

Question 1

what is reflection and refraction

Answer 1

Reflection is the bouncing off of light off a surface. Refraction is the bending of light as it slows down or speeds up as it moves from one optical medium to another.

Question 2

what is Diffraction

Answer 2

Diffractionis the ability of a wave to spread out in wavefronts as the wave passes

Question 3

what is a transverse wave

Answer 3

A transverse waveis a wave in which the particles of the medium vibrate at right angles to the direction of motion of the wave. A transverse wave is a succession of transverse pulses.

Question 4

what is Wavefront

Answer 4

AAn imaginary line joining points on a wave that are in phase.

Question 5

what is superposition

Answer 5

Theprinciple of superposition states that when two pulses occur in the same place at the same time, the resulting pulse is the sum of the two interfering pulses.

Question 6

what is Constructive Interference

Answer 6

Constructive interference occurs when the resulting amplitude of two or more pulses during interference is greater than the amplitude of the original pulses
their resulting amplitude is greater in magnitude than each of the original pulses.
