A metal has a work function of 4.80 eV.
Will ultraviolet radiation with a wave length of 385 nm be able to eject a photoelectron from the metal?
Explain about the monochromaticity of laser. Monochromaticity: The light emitted through a laser is monochromatic, that is this is of one wavelength (colour). Although in ca
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
What is the measure of the force of gravity on an object? Force is the vector product of mass and acceleration: F = ma. Weight is a special case of that formula, where you subs
Two trains simultaneously leave the same train station at noon. One train travels north and the other travels south. The position-time graph or both trains is shown in the accompan
Voltmeters: Voltmeters are used to measure emf's and more commonly potential differences. The two probes of the meter are therefore connected to the two points between which th
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
calculate the frequency of radiation which must be incident on a substance placed in magnetic field strength so that the electron can absorb energy
what is the acceleration due to gravity?
What do you mean by dispersion of light? What is deviation given by a thin prism of angle 80 and refractive index is 1.5? For what angle of incidence, Snell's law is not working
If two soap bubbles of different radii are connected by a tube then, what happen? Ans) When these bubbles are joined through tube..the smaller bubble(with more pressure) gets its
