Spectroscopy Basics

Electromagnetic waves vary in

• the speed they travel in a vacuum.

• wavelength and frequency.

• the way they reflect.

• the orientation of their electric and magnetic fields.

To calculate the frequency of an electromagnetic wave, you need to know the speed of the wave and its

• wavelength.

• intensity.

• refraction.

• amplitude.

Light acts like

• a wave.

• a particle.

• Both a wave and a particle

• neither a wave nor a particle.

Light in the form of a particle that has discrete amount of energy is called a

• Charm

• Photon

• Exciton

• Muon

Electromagnetic radiation is also called as light

• True

• False

Emission of light from an atom occurs when an electron

• drops from a higher to a lower energy level.
•    jumps from a lower to a higher energy level.   
•    moves within its atomic orbital.
• falls into the nucleus.

Monochromatic light means light of a single ____________

• Intensity

• Wavelength

• Velocity

• Frequency

The Velocity of electromagnetic radiation is

• None of the above
