Electromagnetic Waves / Behavior of Light

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

• wavelength.

• intensity.

• refraction.

• amplitude.

• Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma

• Gamma, X-ray, Ultra, Vis, Infra, Micro, Radio

• Vis, Micro, Infra, Ultra, X-ray, Gamma, Radio

• Micro, Radio, Vis, Infra, Ultra, X-ray, Gamma

Which has the LONGEST wavelength and, therefore, the LOWEST frequency/energy

• Gamma Rays

• Ultraviolet

• Visible Light

• Infrared rays

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern

All electromagnetic waves are...

• transverse waves and have the same frequency

• transverse waves and have the same speed

• mechanical waves and have the same wavelength

• longitudinal waves and have the same energy

How is a light wave created differently than a sound wave?

• An electron vibrating making photons vs. a guitar string vibrating to move the air molecules around it

• An electron vibrates to move air molecules vs. a guitar string vibrating to make photons

• they are both vibrating electrons but light makes photons and sound moves air molecules

• they both make photons, but light is from vibrating electrons and sound is from vibrating strings or other objects

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.

An electromagnetic wave in a vacuum has a wavelength of 0.07m. What is its frequency?

• f= 3.0x 10^8 m/s

• f= 3.0x 10^9Hz

• f=4.3x 10^9Hz

• f=4.3x 10^8m/s

Light acts like

• a wave.

• a particle.

• Both a wave and a particle

• neither a wave nor a particle.

The full range of frequencies of electromagnetic radiation is called

• visible light.

• radio waves.

• the electromagnetic spectrum.

• invisible radiation.
