Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged. If the object inside the box was made of a material with a refractive index less than 1.5 then the

A long, straight wire, carrying a current 200A, runs through a cubical wooden box, entering and leaving through holes in the centre of opposite faces (as shown in Fig). The length of each side of the box is 20 cm. Consider an element dl,0.100 cm long of the wire at the centre of the box. Compute the magnitude dB of the magnetic field produced by this element at the point a, b,c,d and e as shown fig. Points a,c, and dare at the centres of the faces of the cube, point b is at the midpoint of one edge, and point e is at a corner. Copy the figure and show the direction and relative magnitudes of field vectors.

A ray of light, travelling parallel to diameter of a sphere enters the sphere through a hole at point A as shown in the figure. The inner surface of the sphere is made perfectly reflecting. Find the number of reflections suffered by the ray before coming out of the sphere.

Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged. She measured the angles of incidence for both the rays on the left side of the box to be 48.6^(@) . She knew the refractive index of the material ‘X’ inside the box was 1.5. What will be the approximate value of angle of refraction? (use the value: sin 48.6^(@) ~~ 0.75 )
