A wedge-shaped thin glass plate of refractive index 1.52 is used to observe fringes of equal thickness. The fringe spacing is 1 mm and the wavelength of light used is 5893 Å. Calculate the angle of the wedge.

A wedge-shaped thin glass plate of refractive index 1.52 is used to observe fringes of equal thickness. The fringe spacing is 1 mm and the wavelength of light used is 5893 Å. Calculate the angle of the wedge.
Answer : To calculate the angle of the wedge, we can use the formula for fringe spacing in a thin wedge-shaped air film. The formula for the fringe spacing \( \Delta x \) is given by: \[ \Delta x = \frac{\lambda}{ ... {-3}} \] Let's calculate it. The angle of the wedge is approximately \( 0.0111^\circ \)....
