About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.

When an electron and its antiparticle positron come close enough to each other, they completely convert into radiation energy in the form of photons, this process is called:
The speed of light in the vacuum is the same for all observers regardless of their relative motion or the motion of the source of the light", is the important postulate of:
In a photoelectric effect experiment the stopping potential is:
In the Compton Scattering experiment the X-ray wavelength change Δλ is _. Here h is Planck constant, m rest mass of electron and θ is angle after scattering.
If the time interval between the occurrence of two events is measured in a frame with no relative motion in which two events occur. Then the time measured by the observer in a frame moving with relative velocity v is _.
Momentum of a photon is
