Wave Optics Tes...

In an interference pattern produced by two identical slits, the intensity at the site of the central maximum is I. The intensity at the same spot when either of the two slits is closed is $$I_{\circ}$$. We must have:

Human eye:

For the propagation of light wave, medium is required. This is according to

According to Maxwell , most of the optical properties of light depend on

According to Huygens, the ether medium pervading entire universe is

In YDSE, the slit widths are in the ratio of $$1: 9$$.The ratio of intensity of the maxima to that of the minima is :

Two periodic waves of intensities I1 and I2 pass
through a region at the same time in the same
direction. the sum of the maximum and
minimum intensities is -

To increase both the resolving power and magnifying power of a telescope

An electron microscope is superior to an optical microscope in terms of:

The angular resolution of a telescope of 10 cm diameter at a wavelength of 5000Å is of the order of:
