Answer :
Laser light passing through two small slits produces a bright fringe centered at the midpoint on a distant screen because the light waves travel the same distance from each slit to the midpoint.
Considering that light is composed of both electric and magnetic fields, it often acts as an electromagnetic wave. Magnetic fields oscillate perpendicularly to the wave propagation direction and are perpendicular to one another. They are called transverse waves as a result of this. The following are a few traits of light:
When dealing with light waves, the sine waveform is used. One complete sweep from 0 to 360 degrees makes up the waveform's period. The wavelength and frequency of light waves are two crucial properties. The wavelength is the distance separating the wave's peaks. Light waves have wavelengths that are on the order of nanometers.
