IPC Fall Final Review 2

Front

What is fusion?

Back

Fusion is a nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is fission?

Back

Fission is a nuclear reaction in which a heavy atomic nucleus splits into two or more lighter nuclei, along with the release of energy.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation into a different element or isotope.

Front

What is the half-life of a substance?

Back

The half-life of a substance is the time required for half of the quantity of the substance to decay or be eliminated.

Front

How much iodine-131 is left after 24 days if the initial amount is 10 mg and the half-life is 8 days?

Back

1.25 mg.

Front

What do all waves transfer?

Back

All waves transfer energy.

Front

What is an echo?

Back

An echo is a sound wave that reflects off a hard surface and returns to the listener.

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium, and it determines the loudness of the sound.

Front

What is frequency in the context of sound waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz), and it determines the pitch of the sound.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.
