Hi.
00:02
In young's double slit experiment, option a, this experiment is evidence for the wave nature of light.
00:49
So this statement is true.
00:53
Now the second statement says that to justify the second statement we use the concept that path difference should be integral multiple of wavelength for the maxima to be obtained on the screen.
01:35
So for second maxima other than the central maxima so we can say the first maxima because second maxima it is including the central maxima so if we if we exclude the central maxima then it will be the first maxima so the condition the part difference for the second maxima as it is given by n lambda so for the first maxima excluding this central maxima n will be equal to 1, so it will come out to be x equals to lambda.
02:20
And here the second statement is saying that the part difference for the first maxima is equal to one wavelength.
02:27
Hence this second statement is also true.
02:32
Now the third statement says it deals with the fringe width on the side.
02:40
Screen and the fringe width on the screen is given as the product of the screen separation from the slits with the wavelength and divided by small d the separation between the two slits so if d is increased means the separation between the two slits if it is increased the fringe width d will be reduced or we can say compressed hence, we can say the third statement is also true...
