MCQ
The tail of the comet is due to
- ✓Vaporisation of water on the comet
- BSublimation of vapour in the comet
- CCooling of water in the comet
- DVaporisation of heat in the comet
✓
Answer
Correct option: A.
Vaporisation of water on the comet
a
(a)If a comet approaches the sun, the substances like water etc. on the comet, get vaporised due to the heat of Sun, and radiation pressure forces of these vapours move away from the Sun. Hence, it forms the tail of the comet.

→Assertion : Newton’s rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is dark.
Reason : The reflection is Newton’s ring cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.

In a cathode ray tube, what is the effect on the beam of particles if the anode voltage is increased ?
A beam of light from a source $L$ is incident normally on a plane mirror fixed at a certain distance $x$ from the source. The beam is reflected back as a spot on a scale placed just above the source $L.$ When the mirror is rotated through a small angle $\theta$, the spot of the light is found to move through a distance $y$ on the scale. The angle $\theta$ is given by
