Light properties, Emission Spectra & the Bohr Model

Front

What must an electron do to change from ground state to an excited state?

Back

Absorb energy.

Front

What does the term 'emission' mean in the context of emission spectra?

Back

Emission refers to the process where energy is being emitted or released by the atom.

Front

Which drawing represents the process by which an emission line is formed?

Back

Drawing D.

Front

What is the ground state of an atom?

Back

The ground state is the lowest energy state of an atom.

Front

Which type of rays carry the greatest amount of energy?

Back

Gamma rays.

Front

What happens to an electron when it absorbs energy?

Back

It transitions from a lower energy level to a higher energy level (excited state).

Front

What is the relationship between electron transitions and emission spectra?

Back

When electrons transition from a higher energy level to a lower one, they emit energy in the form of light, creating an emission spectrum.

Front

What is the significance of the Bohr model in understanding atomic structure?

Back

The Bohr model describes the quantized energy levels of electrons in an atom and explains how electrons can transition between these levels.

Front

How is the wavelength of light related to the energy of the emitted photon?

Back

The energy of a photon is inversely proportional to its wavelength; shorter wavelengths correspond to higher energy.

Front

What is the formula to calculate the energy of a photon?

Back

E = h * f, where E is energy, h is Planck's constant, and f is frequency.
