Assertion : Interference pattern is made by using yellow light instead of red light, the fringes become narrower.
Reason : In YDSE, fringe width is given by β=λD/d
  • a)
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • b)
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • c)
    If the Assertion is correct but Reason is incorrect.
  • d)
    If both the Assertion and Reason are incorrect.

The fringe width is given by
β=λD/d
The fringe width is directly proportional to the wavelength.
The wavelength of blue light is less than that of the red light. So, for blue light the fringe will be narrower.
So, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion : Interference pattern is made by using yellow light instead of red light, the fringes become narrower.

Reason : In YDSE, fringe width is given by β=λD/d

The correct answer is option 'A' - If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Explanation:

Interference patterns are formed when two or more waves overlap and interfere with each other. In Young's double-slit experiment (YDSE), a coherent light source is passed through two narrow slits, creating two coherent sources of light that interfere with each other. The resulting pattern of bright and dark fringes is known as an interference pattern.

Assertion: Interference pattern is made by using yellow light instead of red light, the fringes become narrower.

When the color of light used in the YDSE is changed, it affects the fringe pattern. The assertion states that when yellow light is used instead of red light, the fringes become narrower.

Reason: In YDSE, fringe width is given by β=λD/d

The reason provided states that the fringe width in YDSE is given by β=λD/d, where β represents the fringe width, λ represents the wavelength of light used, D represents the distance between the screen and the double-slit, and d represents the separation between the two slits.

Explanation:

The fringe width in Young's double-slit experiment is determined by the wavelength of light used. The formula β=λD/d shows that the fringe width is inversely proportional to the wavelength of light.

When yellow light is used instead of red light, the wavelength of the light decreases. Since the fringe width is inversely proportional to the wavelength, a decrease in wavelength leads to a decrease in fringe width. This means that the fringes become narrower when yellow light is used instead of red light.

Therefore, both the assertion and the reason are correct. The reason provides a correct explanation for the assertion. The change in the color of light affects the fringe width in YDSE, and the formula for fringe width confirms this relationship.
