Bohr Model, EMR, and Spectra 2024

Front

What is the Bohr model of the atom?

Back

The Bohr model describes the atom as having a nucleus surrounded by electrons that travel in specific orbits or energy levels. It quantizes the energy of electrons, meaning they can only occupy certain energy levels.

Front

What is electromagnetic radiation (EMR)?

Back

Electromagnetic radiation (EMR) is a form of energy that travels through space at the speed of light and includes a range of waves such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

The relationship is given by the equation c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. As wavelength increases, frequency decreases, and vice versa.

Front

Which color of visible light has the shortest wavelength?

Back

Indigo has the shortest wavelength among visible light colors.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.0 x 10^8 m/s.

Front

What is the order of electromagnetic waves from longest to shortest wavelength?

Back

The order is: Radio, Micro, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

What type of electromagnetic radiation can be felt as heat?

Back

Infrared radiation can be felt as heat.

Front

What do the circles in the Bohr model represent?

Back

The circles in the Bohr model represent the energy levels of electrons in an atom.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from about 400 nm (violet) to 700 nm (red).

Front

How does the energy of an electron change when it moves to a higher energy level?

Back

When an electron moves to a higher energy level, it absorbs energy, which allows it to overcome the attraction of the nucleus.
