If three identical prisms are combined is it possible to pass a beam that emerges undeviated? Undispersed?

A crown glass prism of angle 5^(@) is to be combined with a flint prism in such a way that the mean ray passes undeviated. Find (a) the angle of the flint glass prism needed and (b) the angular dispersion produced by the combinatino when white light goes through it. Refractive indices for red, yellow, and violet light are 1.541, 1.517 and 1.523, repectively, for crown flass and 1.613, 1.620 and 1.632 for flint glass.

Three identical resistors are connected in series . When a certain potential difference is applied across the combination , the total power would be dissipated is 27 W . How many times the power would be dissipated if the three resistors were connected in parallel across the same potential difference ?

A prism can produce a minmum deviation delta in a the beam. If three such prisms are combined, the minimum deviation that can be produced in this beam is

The refractive indices of the crown glass for violet and red lights are 1.51 and 1.49 respectively and those of the flint glass are 1.77 and 1.73 respectively A prism of angle 6^(@) is made of crown glass .A beam of white light is incident at a small angle on this prism.The other thin flint glass prism is combined white the crown glass prism such that te net mean deviation is 1.5^(@) anticlockwise. (i)Determine the angle of the flint glass prism. (ii)A screen is placed normal to the emerging beam at a distance of 2m from the prism combination.find the distance between red and violet spot on the screen Which is the topmost colour on screen.

A crown glass prism of angle 5^@ is to be combined with a flint glass prism in such a way that the mean ray passes undeviated. Find (a) the angle of the flint glass prism needed and (b) the angular dispersion produced by the combination when white light goes through it. Refractive indices for red, yellow and viloet light are 1.514, 1.517 and 1.523 respectively for crown glass and 1.613 1.620 and 1.632 for flint glass.

How will you use two indentical prisms so that a narrow beam of white light incident on one prism emerges out of the second prism as white light ? Draw the diagram.

What is the cause of dispersion of white light through a glass prism Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in inverted position with respect to each other and narrow beam of white light is allowed to fall obliquely on one of the faces of the prisms.

Three identical rods are joined together to form an equilateral triangle frame. Its radius of gyration about an axis passing through a corner and perpendicular to the plane of the triangle is.

How will you use two identical glass prisms so that a narrow beam of white light incident on one prism emerges out of the second prism as white light? draw and label the ray diagram

Figure below shows two identical prisms A and B placed with their faces parallel to each other. A ray of light of single colour PQ is incident at the face of the prism A. complete the diagram to show the path of the ray till it emerges out of the prism B.
