Which of the following statements about electromagnetic
radiation is false?
Many metals emit electrons when light of high enough energy is
shone on them. This observation
brought the classical view of light into question.
The energies of atoms are quantized. When an electron moves from
one energy level to another during
emission, a specific wavelength of light (with specific energy) is
emitted.
A neon sign contains glass tubes filled with neon gas. When
electric current is passed through the tube,
the atoms absorb some of the energy and re-emit it as light.
Due to the large mass of macroscopic objects, the de Broglie
wavelength is extremely small. It is so small
that it is impossible to detect compared to the size of the
object.
Light energy cannot be converted into other forms of energy such as
thermal, sound, chemical,
electrical, mechanical, kinetic, potential.
