When a metal is illuminated with radiation with a wavelength of 152 nm, photoelectrons are ejected with a velocity of 7.9 x 105 m/s.
What is the work function, in eV, of the metal?
1. Solve the TISE in each region to find the stationary wave function, and show that it can be written as ?(x) = Ae ikx +(k-1)/(k+1)Ae ikx x =2k/(k+1)Ae ilx x>0 where
Define the Process - Liquid-Solid-Liquid? A small quantity of water of mass m = 50g in a container at temperature T = 273 K is placed inside a vacuum chamber which is expatria
Ripple tank The concept of reflection and refraction of light waves can be understood by the study of reflection and refraction of waves on water. The water waves travel
(a) Potential energy : An electron operates some potential energy due to this found in the field of nucleus potential energy of electron in nth orbit of radius rn is given by
A roller coaster starts from rest at the top of an 18m hill. The car travels to the bottom of the hill and continues up the next hill that is 10.0m high. How fast is the car moving
When a body or a moving particle repeats its motion along an exact path after regular parts of time, its rotation is said to be Periodic Motion and interval of time is known as per
A coil of resistance 1.5k Ω and 0.25H inductance is connected in parallel with a variable capacitance across a 10V, 8kHz supply. Calculate (a) the capacitance of the capacitor
as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
SECOND DEFINITION OF IMPULSE: It can be described as, "The change in momentum produced by the force of impulse".
Potential free contacts (also known as "dry contacts") are simply contacts which are physically operated with the main device, but not electrically connected to it. For example a m
