A cylinder of height h = 1 m has a narrow vertical slit along its wall running up to a length l = 40 cm from the bottom. The width of the slit b = 1 mm. The cylinder is filled with water with the slit closed. Find the force experienced by the vessel immediately after then slit is opened?

The side wall of a wide vertical vessel of height h=75 cm a narrow slit (vertical) running all the way down to the bottom of the vessel. The length of the slit is l=50 cm and the width is b=1 mm . With the slit closed, water is filled to the top. Find the resultant reaction force of water coming out as the slit is opened. brgt

Coherent light of wavelength lambda" = 500 nm" is sent through two narrow parallel slits in a large vertical wall. The two slits are 5 mu m apart. In front of the wall there is a semi cylindrical screen with its hori- zontal axis at the line running on the wall parallel to the slits and midway between them. Radius of the cylin- drical screen is "R = 2.0 m." Find the vertical height of the second order interference maxima from the centre (O) of the screen.

A cylinder has radius 8 cm. Up to what height (in cm) should it be filled with water so that the thrust on its walls is equal to that on its bottom?

A Lloyd's mirror or length 5 cm is illuminated with mon ochromatic light of wavelength lambda (= 6000 Å) from a narrow 1 mm slit in its plane and 5 cm plane from its near edge. Find the fringe width on a screen 120 cm from the slit and width of interference pattern on the screen.
