The index of refraction of a glass plate is 1.48 at `theta_(1) = 30.^@C` and varies linearly with temperature with a coefficient of `2.5 xx 10^(-5).^@C^(-1)`. At 3`0.^@C`, the length of the glass plate is 3 cm. This plate is placed in front of one of the slit n Young's double-slit experiment. If the plate is being heated so that it temperature increases at a rate of `5^(@)C^(-1)` min, the light sources has wavelength `lambda = 589 nm` and the glass plate initially ia at `theta = 30^@C`. The number of fringes that shift on the screen in each minute is nearly (use approximation)

The index of refraction of a glass plate is 1.48 at theta_(1) = 30.^@C and varies linearly with temperature with a coefficient of 2.5 xx 10^(-5).^@C^(-1) . The coefficient of linear expansion of the glass is 5 xx 10^(-9)^@C^(-1) . At 3 0.^@C , the length of the glass plate is 3 cm. This plate is placed in front of one of the slit n Young's double-slit experiment. If the plate is being heated so that it temperature increases at a rate of 5^(@)C^(-1) min, the light sources has wavelength lambda = 589 nm and the glass plate initially ia at theta = 30^@C . The number of fringes that shift on the screen in each minute is nearly (use approximation)

A thin glass plate is introduced in front of one of the double slits. What will happen to the fringe width?

In a young 's double slit experiment, a glass plate of refractive index 1.5 and thickness 5 times 10^-4 cm is kept in the path of one of the light rays. Then

In a young 's double slit experiment, a glass plate of refractive index 1.5 and thickness 5 times 10^-4 cm is kept in the path of one of the light rays. Then

A transparent glass plate of thickness 0.5 mm and refractive index 1.5 is placed infront of one of the slits in a double slit experiment. If the wavelength of light used is 6000 A^(@) , the ratio of maximum to minimum intensity in the interference pattern is 25/4. Then the ratio of light intensity transmitted to incident on thin transparent glass plate is

In Young's double slit experiment, a glass plate is placed before a slit which absorbs half the intensity of light. Under this case

If a transparent medium of refractive index mu=1.5 and thickness t=2.5xx10^-5m is inserted in front of one of the slits of Young's Double Slit experiment, how much will be the shift in the interference patten? The distance between the slits is 0.5mm and that between slits and screen is 100cm
