15=. In 1920, a young physicist named Louis de Broglie made a radical suggestion that since light has both a particle and wave nature then matter has a wave nature The De Broglie equation states that every particle that moves can sometimes act as a wave, and sometimes as a particle. The wave which is associated with the particles that are moving are known as the matter-wave, and also as the De Broglie wave. The wavelength is known as the de Broglie wavelength. the de Broglie wave equation λ=hmv 16=. Polarization of light is a property that applies to turning waves that shows the geometrical blooming of the oscillations. In a turning wave, the way of the oscillation is ninety degrees of the motion of the wave Firstly the unpolarised light I° passes through the first polaroid ,then intensity of the polarised light become I° /2 ,after passing through the second polaroid I° /2 will be multiplied by cos^2( θ)=1/2 (by malus law),so final intensity will be I°/4 Let I0 be the intensity of polarised light after passing through the first polariser P1. Then the intensity of light after passing through second polariser P2 will be I=I0cos2θ, where θ is the angle between pass axes of P1 and P2. 19. The generation of potential difference in a coil due to the changes in the magnetic flux through it is called Electromotive force. In order to generate dynamically induced EMF, the magnetic field must be kept stationary while the conductor is moving. The equation for dynamically induced EMF is. e = B l v. 20. The magnifying power of a microscope is given by. m=1+Df. where f is the focal length of the lens and D is the least distance of distinct vision for the normal eye. The magnifying power of a microscope can be increased by using a lens of short focal length. But it cannot be increased indefinitely. Class 12 physics ka
