The observed increased in wavelength of
light from distant _______ is called
_______. The _______ away the galaxy
the _______ it is moving & the _______
the increase in wavelength (the bigger the
red shift).
Speed=Wavelength X Frequency
Galaxies; bigger; faster; RED SHIFT;
further

In a transverse waves the ________are
________ to the direction of energy
transfer. In a longitudinal wave the
_______ are ________ to the direction
of energy transfer. This can be
demonstrated using a _______ spring.

Refraction occurs when a wave is
________down as it travels into a
more dense medium (________). The
wave now bends _____ the normal. As
it leaves the dense medium (______)
it ______ up & bends ______from the
normal.

The fuels used in a nuclear power stations are;
U_____________________ & P____________________
Nuclear fraction/fission creates potential/energy in a nuclear power
station. Some say nuclear is a clean resource as it doesn’t make N2/CO2
however the products are radioactive/smelly & could cause environmental
problems.
Label the diagrams below using the
following labels; Liquid; gas; solid;
boiling; condensation; freezing;
sublimation; melting; fast moving;
vibrating ; moving; fixed shape

P1 waves, radiation & energy
________ is the process when waves bend
around corners or through ________ (gaps).
When the gap is almost the ______size as the
wavelength, the greater the diffraction
effects. When waves meet an ______
(mountain, see right) the ______ the
wavelength the more diffraction occurs.
