The magnifying power of a simple microscope can be increased if we use eye piece of

In a simple form of astronomical telescope the focal length of the objective is 30 cm and that of the eye piece is 2 cm. The magnifying power, when the final image of a distant object is seen at a distance of 12 cm, is

In a double slit experiment, the distance between the two slits 1 mm and the screen is placed 1 m way. What should be the width of each slit to obtain 20 maximum of the double-slit pattern within the central maximum of the single slit pattern.

A beam of natural light falls on a system of 6 polaroids which are arranged in succession such that each Polaroid is turned through 30⁰ with respect to the preceding one. What portion of the incident energy passes through the system?

In the young’s double slit experiment the interference pattern is found to have intensity ratio between bright and the dark fringes as 9. This implies that

The shortest wavelength of X-ray emitted from a X-ray tube depends on the

The minimum wavelength of X-ray produced by electrons accelerated by a potential difference of V volt is equal to

Transverse waves can propagate

The ratio of the velocities of sound in hydrogen and carbon dioxide at S.T.P. is

A transverse wave is described by the equation. The maximum particle velocity is equal to four times the wave velocity if
