Which experiment seemed to make it clear that light propogates as a wave?
Wave front formed by the collimator of a spectrometer
Indentify the correct statement from the following
Huygen's concept of secondary wave
The wavefront of a lightbeam is given by the equation $x+2y+3z=c$,(where c is arbitary constant) the angle made by the direction of light with the y-axis is:
In which of the following cases do we obtain a plane wave front?
The two coherent sources of equal intensity produce maximum intensity of $100$ units at a point. If the intensity of one of the sources is reduced by $50\%$ by reducing its width then the intensity of light at the same point will be
For what distance ray optics a good approximation when the aperture is 4 mm wide and the wavelength is 500nm?
A monochromatic light is incident on a single slit of width $24\times 10^{-5}\ cm$. Calculate wavelength of light if angular position of $1^{st}$ secondary maxima is $30^{o}$.
At the first minimum adjacent to the central maximum of a single slit diffraction plate the phase difference between the huygens wavelet from the edge of the slit and the wavelet from the midpoint of the slate
