EQUATIONS OF MOTION WITH CONSTANT (UNIFORM) ACCELERATION
Example 1
A cyclist starts from rest and accelerates uniformly for 16 s at 0.75 m/s2 [W]. She then
cycles at a constant velocity for 55 s, then slows to a stop with an acceleration of 0.60
m/s2 [E].
Generators
An important application of electromagnetic induction is in the generation of electric
current. AC generators produce an electric current via the motion of coils in a magnetic
field or by rotating a magnet within a stationary coil. The term alt

Diffraction
Diffraction is the bending of a wave as the wave passes through an opening or by an
obstacle. The amount of diffraction depends on the wavelength of the waves and the
size of the opening.

POLARIZATION
Polarization is the process in which a wave is allowed to vibrate in one plane. In such a
case the wave is said to be plane polarized. Polarization is a strong indication that light
behaves as a transverse wave. An ordinary beam of light can
