A narrow beam of white light goes through a slab having parallel faces.

A

The light never splits in different colours

B

The emergent beam is white

C

The light inside the slab is split into different colours

D

The light inside the slab is white

Text Solution

Verified by Experts

The correct Answer is:
b,c
The light splits in different colours inside the slab due to dispersion.
But the emergent rays will be paeallel and will overlap with others hence giving white emergent beam. Inside the slab rays of different colours are not parallel and they intersect each other.

A narrow beam of light passes through a slab obliquely and is then received by an eye. The index of refraction of the material in the slab fluctuates slowly with time. How will it appear to the eye? The twinkling of stars has a similar explanation.

The diagram shown below in Fig. 6.8 shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism. If the yellow light is replaced by a narrow beam of white light incident at the same angle, draw another diagram to show the passage of white light through the prism and label it to show the effect of the prism on the white light.

Draw a ray diagram showing the dispersion through a prism when a narrow beam of white light is incident on one of its refracting surface. Also indicate the order of the colours of the spectrum obtained.

A narrow and parallel beam of white light is incident on a convex lens, parallel to its principal axis. Draw a labelled diagram to show how coloured images are formed by the lens.

A beam of unpolarised light passes through a tourmaline crystal A and then it passes through a second tourmaline crystal B oriented so that its principal plane is parallel to that of A. The intensity of emergent light is I_(0) . Now B is rotated by 45^(@) about the ray. The emergent light will have intensity
