Question 1

Electromagnetic radiation

Answer 1

Radiation that exhibits wave-like behavior and travels through space at the speed of light in a vacuum

Question 2

Wavelength

Answer 2

The distance between two consecutive peaks or troughs in a wave

Question 3

Frequency

Answer 3

The number of waves (cycles) per second that pass a given point in space

Question 4

Photon

Answer 4

A particle of electromagnetic radiation

Question 5

Quatanized

Answer 5

(Quantization) the concept that energy can occur only in discrete units called quanta

Question 6

Ground state

Answer 6

The lowest possible energy state of an atom or a molecule

Question 7

Excited state

Answer 7

A state of excess energy in an atom or molecule

Question 8

Examples of electromagnetic radition

Answer 8

.Gamma-rays. Gamma rays have the highest frequency and photon energy in the electromagnetic spectrum
.X-rays. X-rays have frequencies and photon energies slightly lower than gamma rays.
.Ultraviolet (UV) Rays
.Visible light
.Infrared (IR) Rays
.Radio Waves
.Microwaves

Question 9

Describe the relationship between frequency and waveleng

Answer 9

As the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Question 10

Describe the relationship between energy and wavelength

Answer 10

As a wavelength increases in size, its frequency and energy (E) decrease

Question 11

Answer 11

Speed of light (2.998x10^8)

Question 12

Describe the speed of light

Answer 12

Speed of light (2.998x10^8)
