100
the phenomenon of the spreading of a wave after an aperture or obstacle.
What is diffraction
200
the probability of decay of a nucleus per unit time
What is the decay constant?
200
theory stating that all moving particles have a ‘matter wave’ associated with them.
What is the de Broglie hypothesis?

It is impossible to distinguish between the effects of a gravitational field and acceleration?
What is the equivalence principle?
200
slows down fast moving neutrons to allow further nuclear reactions to take place
What is a moderator

The amplitude of this wavefunction gives the probability of finding the electron at a particular point.
What is Schrödinger equation?
300
The time interval between two events at the same point in space.
What is proper time?
300
useful energy stored per unit volume or per unit mass depending on the fuel
What is energy density
300
a lens defect due to the fact, of incident rays parallel to the principal axis, only those close to the principal axis refract through the focal point
What is spherical aberration
400
difference between measured mass of a nucleus and the total mass of the nucleons
What is mass defect?
400
The theory that states the quantities, position & momentum and time & energy, cannot be known precisely at the same time.
What is Heisenberg principle?
400
An experiment designed to measure the speed of the earth relative to the ether.
What is Michelson-Morley experiment?
400
the ratio of the power that is scattered (reflected) from the surface compared to total incident power received.

400
The shortest distance at which the eye can focus without straining comfortably

500
An experiment in which clocks taken on board a fast moving plane differed from similar clocks on earth.
What is the Hafele-Keating experiment.
500

What is the Stefan-Boltzmann law
500
