WAVE OPTICS
Wave Optics Quiz
If you are ready to dive into the fascinating world of wave optics, this quiz is designed for you! Test your knowledge on various topics such as interference, polarization, and the fundamental concepts of optics.
Challenge yourself and see how well you understand:
- Resolving power and its determinants
- Principles of light behavior and phenomena
- Applications of optics in real-world scenarios
Resolving power of telescope can be increased by increasing
The wavelenght
The diameter of object
The diameter of eyepiece
The focal length of eyepiece
Polarisation of light proves
Corpuscular nature of light
Quantum nature of light
Transverse wave nature of light
Longitudinal wave nature of light
The wavefront due to a source situated at infinity is
Spherical
Cylindrical
Planar
Circular
A laser beam is coherent because it contains
Waves of several wavelengths
In coherent waves of a single wavelengthss
Coherent waves of several wavelengths
Coherent waves of a single wavelength
According to Huygens' principle, light is a form of
Particle
Rays
Wave
Radiation
Two coherent monochromatic light beams of intensities I to 4I superimpose. The maximum and minimum possible intensities in the resulting beam are
5I and I
5I and 3I
3I and I
9I and I
When exposed to sunlight, thin films of oil on water of ten exhibit brilliant colours due to the phenomenon of
Interference
Diffraction
Dispersion
Polarisation
What happens , if the monochromatic light used in Young's double slit experiment is replaced by white light?
No fringes are observed
All bright fringes becomes while
All bright fringes have colour between violet and red.
Only the central fringe is white and all other fringes are coloured.
When compact disk is illuminated by a source of white light, coloured lines are observed. This is due to
Dispersion
Diffraction
Interference
Refraction
Resolving power of microscope depends upon
Wavelenght of light used (directly propportional)
Wavelength of light used ( inversely proportional)
Frequency of light used
Focal length of objective
The phenomenon of interference is based on
Conservation of momentum
Conservation of energy
Conservation of momentum and energy
Quantum nature of light
A double slit interference experiment is carried out in air and the entire arrangement is dipped in water. The fringe width
Increases
Decreases
Remains unchanged
Fringe patter disappears
In Young's double slit experiment, if the monochromatic sources of yellow light is replaced by red light, the fringe width
Increases
Decreases
Remains unchanged
The fringes disappear
The idea of secondary wavelets for the propagation of a wave was first given by
Newton
Huygens
Maxwell
Fresnel
Light propagates rectilinearly, due to
Wave nature
Wavelengths
Velocity
Frequency
