Assertion: White light is used in YDSE. ...

Assertion: White light is used in YDSE. Now, a glass slab is inserted in front of the slit `S_1`. Then, red fringe will shift less (in upward direction) compared to violet.
`
Reason: Refractive index for violet colour will be more.

A

(a)If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

(b)If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false, but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Shift = `((mu-1)tD)/d` is independent of lambda.

Assertion In the YDSE set up shown in figure a glass slab is inserted in front of the slit S_(1) as shown in figure Then zero order maxima (where path difference =0) will lie above point O. Reason Glass slab will produce an extra path difference in the path of the ray passing through S_(1)

Assertion: If white light is used in place of monochromatic light in YDSE, then central point is white, although at other places coloured fringes will be obtained. Reason: At centre, path difference is zero for all wavelengths. Hence, all wavelengths will interfere constructively.

Assertion (A): The light of violet colour deviates the most and the light of red colour the least, while passing through a prim. Reason (R):The refractive index in highest for red light and lowest for the violet light.

Assertion: Speed of light in glass is indep[endent of the colour of light. Reason : the violet colour travels faster than the red light in a glass prism.

Assertion:- When a white light is passed through a lens, Violet light is more deviated than red light. Reason:- wave- length for red light is greater than violet

White light is used in a Young's double slit experiment. Find the minimum order of the violet fringe (lamda = 400 nm) which overlaps with a red fringe (lamda = 700 nm) .

Interference fringes were produced in Young's double-slit experiment using light of wavelength 5000 Å . When a film of thickness 2.5xx10^(-3) cm was placed in front of one of the slits, the fringe pattern shifted by a distance equal to 20 fringe-widths. The refractive index of the material of the film is
