A monochromatic light of wavelength 6000Å is incident on a plane diffraction grating with grating element 6 X 10-5 cm. Evaluate the maximum order of spectrum that will be observed?
A monochromatic parallel beam of light is incident on a single slit. Graphically show the intensity distribution among the secondary maxima and principle maxima in diffracted beam.
In these diodes electron and hole pairs are formed by junction photoelectric effect. That is the covalent bonds are broken by the EM radiations absorbed by the electron in the V.B.
In a Newton's rings experiment in laboratory source of light having two wavelengths 6000Å and 4500Å is used. It is found that n th dark ring due to 6000Å coincides with
(i) It has of continuously varying wavelengths in a exact wavelength range. (ii) It is given by solids, liquids and highly compressed gases heated to high temperature. (iii)
Magnetic Susceptibility and Ferromagnetic Substances: Magnetic Susceptibility: The magnetic susceptibility (c) of a substance is defined as the ratio of the intensity of magn
Light with a wavelength of 454.5 nm passes by two slits that are 95.2 cm from a screen. The distance among the centers of the central band and the first-order band is 15.2 mm.
INTRODUCTION: Superconductivity is a phenomenon takes place in certain materials at low temperatures. Characterized by precisely zero electrical resistance. Superconductors have
two forces of 20 units and 30 units act at right angle what is the magnitude of resultant force
Can the batteries used in the torch lights be recharged after their discharge? Give reason? Ans) No,because the NH4Cl corrods the zn containger gradually.so with out anode redox
