Question

How small are the wavelengths of gamma ray radiation? A. smaller than an atom B. about the size of a golf ball C. about 10 times the size of an atom D. about the size of earth **:( thank you!!

Answer 1

Electromagnetic waves about the size of a golf ball are used for
microwave radio communication and radar every day.

Electromagnetic waves that are about 4-1/2 inches long are used
in the microwave oven to heat leftover meatloaf and make popcorn .

Electromagnetic waves that are 10 times the size of an atom
are hard hard X-rays.

Electromagnetic waves that are the size of Earth's diameter
are used for ELF communications, including standard time
signals, and submarine communication.

Mechanical waves that are the same order of magnitude as
the Earth are seismic (earthquake) waves.

Gamma rays are electromagnetic waves with wavelengths in the
neighborhood of the same size as the atomic nucleus. To get
some idea of their frequency, just contemplate how long it would
take light ... (which can get to the moon in a couple of seconds) ...
to move from one side of an atomic nucleus to the other side.

Answer 2

The correct answer is: A. Smaller than an atom.
