Gravity
This physicist proposed the theory of general relativity, which describes gravity as the curvature of spacetime.
Albert Einstein
This type of wave does not require a medium to propagate and can travel through a vacuum.
electromagnetic wave
The energy of motion is known as this.
kinetic energy
This famous experiment conducted in 1919 provided evidence supporting Einstein's theory of general relativity.
Eddington Eclipse Experiment
wavelength
What is the unit of measurement for gravitational force?
Newton (unit)
What is the name of the phenomenon where an object's frequency appears to change due to motion relative to an observer?
Doppler effect
What term describes the smallest possible quantity of energy that can be emitted or absorbed in the form of electromagnetic radiation?
quantum
What is the name of the theoretical particles associated with the transmission of gravitational force?
gravitons
thermal energy
What is the name of the force that pulls objects toward the center of the Earth?
gravity
These waves are produced by the acceleration of charged particles and can travel through space.
electromagnetic waves
This law of physics states that energy cannot be created or destroyed, only transformed from one form to another.
the law of conservation of energy
The speed of light is a fundamental constant denoted by this letter.
"c" (speed of light)
principle of diffraction
The force of gravity between two objects depends on these two factors.
mass and distance
What type of wave consists of oscillations perpendicular to the direction of propagation?
transverse wave
This type of energy is stored in an object due to its position or configuration.
potential energy
This famous equation, E=mc^2, relates energy and mass.
mass-energy equivalence equation
mechanical energy
This type of wave is characterized by compressions and rarefactions and requires a medium for propagation.
a sound wave
What is the term for the bending of waves around obstacles or through openings?
diffraction
The study of the behavior of waves is known as this branch of physics.
wave mechanics
What is the name of the process where light is absorbed by atoms and then re-emitted in all directions?
absorption and emission
longitudinal wave
