A wave pulse traveling on a two piece string, gets partially reflected and partially transmitted at the junction. The reflected wave is inverted in shape as compared to incident one. If the incident wave has wavelength $\lambda$ and transmitted wave has $\lambda ',$ then
The wave front due to a point source at a finite distance from the source is -
Particle nature and wave nature of electomagnetic waves can be shown by
Which of the following statements indicates that light waves are transverse
On a hot summer night,the refractive index of air is smallest near the ground and increases with height from the ground. When a light beam is directed horizontally , the Huygen's principle leads us to conclude that as it travel,the light beam:
Huygens' principle is used to
When light suffers reflection at the interface between water and glass, the change of phase in the reflected wave is
On reflection from a plane surface, the following two characteristics get changed :
Huygen's originally thought that for the propagation of light waves wavefront is required.
The wave theory of Light was proposed by ...............
