Light and Electrons

Front

What is an electron?

Back

An electron is a subatomic particle that has a negative charge and much less mass than a proton.

Front

What is the electron configuration of Chlorine (Cl)?

Back

The electron configuration of Chlorine (Cl) is 1s² 2s² 2p⁶ 3s² 3p⁵.

Front

What is the relationship between energy and wavelength in waves?

Back

Higher energy waves have shorter wavelengths.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

How does wavelength relate to frequency?

Back

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

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What type of wave has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.

Front

What is the formula to calculate the speed of a wave?

Back

The speed of a wave is calculated using the formula: speed = frequency × wavelength.

Front

What is the significance of the quantum model of the atom?

Back

The quantum model describes electrons as existing in probabilistic orbitals rather than fixed paths.
