The splitting of a spectral line into several components in the presence of a static magnetic field.

No engine operating between two temperatures can be more efficient than a reversible engine working between the same two temperatures.

The force between any two charges is directly proportional to the product of charges and inversely proportional to the square of the distance between the charges.

The apparent change in the frequency of a wave due to relative motion between the source and the observer.

It is impossible to have a particle that has an arbitrarily well-defined position and momentum at the same time.

The emission of electrons in some materials when light of suitable frequency falls on them.

The ratio of normal stress to the longitudinal strain produced in a body.

A body immersed in a fluid experiences an apparent loss in weight which is equal to the weight of the fluid displaced by the body.

For a given mass of a gas at constant temperature, the volume of the gas is inversely proportional to the pressure.

Within elastic limit, stress is directly proportional to strain.

A body continues in a state of rest or of uniform motion in a straight line unless it is acted upon by an external (unbalanced) force.

The current flowing through a conductor is directly proportional to the potential difference across the ends of the conductor.

Two identical fermions cannot occupy the same quantum state simultaneously.

The amount of energy radiated per second per unit area of a perfectly black body is directly proportional to the fourth power of the absolute temperature of the surface of the body

If body A is in thermal equilibrium with body B, and B is also in thermal equilibrium with C, then A is necessarily in thermal equilibrium with C.

Under the same conditions of temperature and pressure, equal volumes of all gases contain equal number of molecules.

The total energy per unit volume of a non-viscous, incompressible fluid in a streamline flow remains constant.

States that the refractive index of a material is equal to the tangent of the polarizing angle for the material.

Each point on a light wavefront can be regarded as a source of secondary waves, the envelope of these secondary waves determining the position of the wavefront at a later time.

The pressure exerted on a liquid is transmitted equally in all directions.
