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?
How are amps and watts related? In a nutshell, the power (measured in watts) dissipated by a resistance is directly proportional to the square of the current (measured in amper
What is Ancient view Ancient view: objects tend to stay if they are in motion; force is needed to keep something moving. This was a natural thing to believe in because we see

An electron in the hydrogen atom loses 3.02 eV as it falls to energy level E 2 . From which energy level did the atom fall?
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
