Which of the following phenomena produces the colour in soap bubble?
1 Diffraction
2 Interference
3 Polarisation
4 Refraction
Explanation:
: As the position of eyes is changed, path difference corresponding to different wavelength of the light emitted by the bubble change. Thus, the intensities of different wavelength one different, resulting the bubble to be opened coloured.

Standing waves are formed on a string when interference occurs between two waves having
1 the same amplitude travelling in the same direction with no phase difference between them
2 the same amplitude, travelling in the opposite direction with no phase difference between them
3 different amplitudes travelling in the same direction
4 different amplitudes travelling in the opposite direction
Explanation:
: When two identical transverse of longitudinal, progressive wave travel in a bounded medium with the same speed, but in opposite directions, then by their superposition a new type of wave is produced which appears stationary in the medium. This is called stationary wave.

Which of the following is wrong for interference fringes?
1 Fringes are due to limited portion of wave front
2 All bright fringes are equally bright
3 Distance between two consecutive fringes is constant
4 Fringes are due to the use of coherent sources
Explanation:
: Interference fringes are formed due to the whole portion of wave front not due to limited portion of wave front.

As a result of interference of two coherent waves, energy is
1 increased
2 decreased
3 redistributed and distribution change with time
4 redistributed and distribution does not change with time
Explanation:
: When two coherent wave interfere to each other then pattern contains both maxima and minima. This means that the energy emitted by two coherent sources are redistributed in this fringe pattern and the distribution is space dependent and time independent.
