Question

यदि प्रकाश स्रोत स्लिट के आकार का हो, तो किस प्रकार का तरंगाग्र बनता है?
If the light source is slit-shaped, then what type of waveform is​

Answer 1

Answer:

Interference is the phenomenon in which two waves superpose to form the resultant wave of the lower, higher or same amplitude. ... This is because light waves are randomly generated every which way by most sources

Answer 2

Young double slit experiment

Explanation:

• Whenever light constructively interferes, the 2 waves act upon each other and form "super light wave." also, whenever light destructively interferes (such as when a crest meets a trough), the 2 waves act to destroy one another and produce no light wave.
• Thus, the two-point source interference pattern would still accommodates an alternating pattern of antinodal lines and nodal lines. However for light waves, the antinodal lines are resembling bright lines and also the nodal lines are akin to dark lines.
• If such an interference pattern might be created by two light sources and projected onto a screen, then there must be an alternating pattern of dark and bright bands on the screen. And since the central line in such a pattern is an antinodal line, the central band on the screen should be a bright band.
• In 1801, Young showcased that light does produce a two-point source interference pattern. so as to supply such a pattern, monochromatic light must be used.
• Monochromatic light is light of one color; by use of such light, the 2 sources will vibrate with the identical frequency. it's also important that the 2 light waves be vibrating in phase with each other; that's, the crest of 1 wave must be produced at the identical precise time because the crest of the second wave. (This is usually mentioned as coherent light.)
• To accomplish this, Thomas young used one light and projected the sunshine onto two pinholes. the sunshine from the source will then diffract through the pinholes and therefore the pattern is projected onto a screen.
• Since there's just one source of sunshine, the set of two waves that emanate from the pinholes are in phase with one another. evidently, the utilization of a monochromatic light and pinholes to come up with in-phase light waves resulted in a very pattern of alternating bright and dark bands on the screen.

The light source from slit shaped will form a diffracted coherent wave
