Monochromatic light (single wavelength) falls on two narrow slits S1 and S2 which are very close together acts as two coherent sources, when waves coming from two coherent sources (S1, S2) superimposes on each other, an interference pattern is verified on the screen. In YDSE alternate bright and dark bands obtained on the screen. These bands are known as Fringes.
450J of energy are changed into heat in 1 minute. What power is dissipated? A current of 10A ?ows by a conductor and 10Wis dissipated. What p.d. exists across the ends of
why CPH has speed Vc and Vc is greater than c? Answer; since you know photon has spin. Thus the path per time of a point on photon is greater than c it means the speed of photo
Q. Give the basic assumptions made in free electron model of solid. OR Write down basic postulates of Sommerfield's free electron gas model. Show that the number of ene
The neutral point in an electrostatic field appears to have a resultant potential. why is this so?
Im having trouble understanding these,, could someone explain them in lamens terms
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
Explain about the single mode fibres in intermodal dispersion. Into single mode fibers, the core size of the fibre is decreased to 3 to 9µm so that this supports simply axial m
A body of mass 500g IS heated such that its température roses from -4*c to 100*c calculate the total heat energy consumed
An object falls from a high tower and lands on a high hill with an alpha angle. Then he jumps while going down the hill. How long is the distance between when the ball landed and t
LENZ’S LAW A change of flux in a closed circuit induces an emf and sets up a current. The direction of this current is such that its magnetic field tends to oppose the c
