Answer:
This whole concept depends on the depends on the direction of propagation of the surface wave or displacement of wave such that if its in direction of wave velocity its said to features of longitudinal wave and if its in direction at 90° to wave velocity its said to have transverse features
motion
vt=vo+at
10 m/s = 2 m/s + 2.2 m/s².t
8 = 2.2t

The spacing between the fringes does not depend on the width of the slit.
The light intensity produced by the slits increases with increased width of the slit. The screen thus develops brighter fringes as the slit width increases.
On the screen, coloured fringes will be created if the white light replaces monochromatic light.
<h3>What is diffraction?</h3>
Diffraction is the breaking up of an electromagnetic wave as it passes a geometric structure (e.g. a slit), followed by reconstruction of the wave by interference. Diffraction occurs for all types of waves, including sound waves.

Mechanical waves transfer energy by including vibration in the propagation medium electromagnetic waves do not require a medium for propagation but still transfer energy by having an electric and magnetic field propagate perpendicular to one another. Hope this helps:)
The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.
