10 Questions
What is the characteristic of ordinary source of light in terms of intensity and divergence?
Low intensity and high divergence
Which type of light waves have the same wavelength and same phase difference?
Monochromatic light
Which postulate of Bohr describes the emission of a photon?
Emission: The electron makes the transition to a lower state and emits a photon whose energy is equal to the energy difference of two states
What type of wavefront does an ordinary source of light emit?
Spherical wavefront
What is the nature of radiation from an ordinary source of light?
Incoherent
Monochromatic light consists of two or more light waves with the same wavelength and different phase difference.
False
Coherent light consists of two or more light waves with the same wavelength and same phase difference.
True
Spherical wavefront indicates light spreading in all directions with low intensity.
True
Plane wavefront indicates light emitting in only one direction with high divergence.
