Q1
What is an X-ray?
An X-ray is a penetrating type of electromagnetic radiation. Almost every x-ray has a wavelength from 10 picometers to 10 nanometers.
Q2
What is a gamma-ray?
A gamma-ray is another penetrating type of electromagnetic radiation generated from the radioactive decay of atomic nuclei. Gamma-ray is made of the shortest wavelength (among the important electromagnetic waves).
Q3
What is meant by radiation?
Radiation is the transmission or emission of energy in the form of particles or waves through a medium or vacuum.
Q4
What is meant by the photoelectric effect?
The photoelectric effect is a process in which electrons are emitted from a metal’s surface when light strikes it.
Q5
Who discovered the Compton effect?
Arthur Compton discovered the Compton effect.
Q6
What is meant by the Compton effect?
The Compton effect is the enlargement of wavelengths of X-rays and other EM waves that have been scattered by electrons. It is a fundamental way in which radiating energy is absorbed by matter.
Q7
What is wavelength?
A wavelength is a length between successive troughs or crests.
Q8
Which symbol is used to represent the Compton wavelength?
Compton wavelength is represented by the letter λ (Lambda).
Q9
What is a photon?
A photon is a fundamental particle that is the force carrier of electromagnetic force. It is massless and travels at the speed of light 299792458 m/s (in vacuum).
Q10
Who explained the photoelectric effect?
Albert Einstein explained the photoelectric effect.
