A beam of parallel light rays is incident through the holes on one side of a box and emerges out through the holes on its opposite side as shown in the diagram below: Which of the following could be inside the box?

A beam of light is incident through the holes on one side of a box emerges out throught holes on its opposite side as shown in the following figure: The box contains:

Figure shows wavefront P Passing through two systems A and B, and emerging as Q and then as R. Then systems A and B could, respectively, be

A point light source of 100W is placed at a distance x from the centre ofa hole ofradius R in a sheet as shown in figure, Find the power passing through the hole in sheet

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.
