The Quantum Atom (Flashcard 24 vers)

Front

What is the relationship between wavelength and frequency?

Back

As frequency increases, wavelength decreases.

Front

What happens to energy as frequency increases?

Back

The energy increases.

Front

What is produced when an electron moves to a lower energy level?

Back

A line spectrum.

Front

What occurs when an electron moves from n=5 to n=2?

Back

It releases energy.

Front

What occurs when an electron moves from n=2 to n=4?

Back

It absorbs energy.

Front

Define wavelength.

Back

Wavelength is the distance between successive crests of a wave.

Front

Define frequency.

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the formula for calculating the speed of a wave?

Back

Speed = Wavelength x Frequency.

Front

What is the relationship between energy and frequency in quantum mechanics?

Back

Energy is directly proportional to frequency.

Front

What happens to the energy of an electron when it moves to a higher energy level?

Back

It absorbs energy.
