1.
Which of the following is not a property of light
2.
In Young's double slit experiment, the distance between the two slits is made half, then the fringe width will become
3.
The phenomenon which does not take place in sound waves is
4.
A mixture of light, consisting of wavelength 
and an unknown wavelength, illuminates Young's double slit and gives rise to two overlapping interference patterns on the screen. The central maximum of both lights coincide. Further, it is observed that the third bright fringe of known light coincides with the 4th bright fringe of unknown light. From this data, the wavelength of the unknown light is
and an unknown wavelength, illuminates Young's double slit and gives rise to two overlapping interference patterns on the screen. The central maximum of both lights coincide. Further, it is observed that the third bright fringe of known light coincides with the 4th bright fringe of unknown light. From this data, the wavelength of the unknown light is
5.
In Young's double slit experiment, the 
maximum with wavelength 
is at a distance 
from the central maximum and the 
maximum with a wavelength 
is at a distance 
. Then 
is equal to
maximum with wavelength is at a distance from the central maximum and the maximum with a wavelength is at a distance . Then is equal to
6.
The idea of the quantum nature of light has emerged in an attempt to explain
7.
A new system of units is evolved in which the values of 
and 
are 2 and 8 respectively. Then the speed of light in this system will be
and are 2 and 8 respectively. Then the speed of light in this system will be
8.
Unpolarised light falls on two polarizing sheets placed one on top of the other. What must be the angle between the characteristic directions of the sheets if the intensity of the final transmitted light is one-third the maximum intensity of the first transmitted beam
9.
Which of the following is electromagnetic wave
