$200

Radio waves

The lowest frequency of electromagnetic radiation is

$400

It is both

Is electromagnetic radiation a wave or a particle?

$600

Visible and radio

Two forms of electromagnetic radiation that penetrate the atmosphere best

are:

$800

Gamma rays

The part of the electromagnetic spectrum with the shortest

wavelength is

$1000

White light is all the colors blended together uniformly

What is white light?

$200

Rainbow

What is an example of a classic continuous spectrum

$400

violet

The visible light with the shortest wavelength is

$600

visible

What type of radiation can be observed well from Earth’s

surface?

$800

red

Which color of electromagnetic radiation has the longest wavelength?

$1000We don’t for sure. Since lightmust travelo millions of light years, the light we see is

millions of years old.

How do we know that a star in a distant galaxy is still

there?

$200

red

Objects we are moving away from appear

$400

Doppler effect

When you hear a siren change pitch as it approaches

you this is an example of

$600

No shift at all (not blue or red) so it will appear yellow

The light from an object moving from right to left will

exhibit

$800

An object moving towards us would appear

blue

$1000

You can give its radial velocity, either towards or away from us.

What information can be inferred about a star from its

Doppler shift?

$200

radio

What type of wave has the lowest energy

$400

halved

If a waves frequency doubles it wavelength is

$600They both transfer energy.

Sound needs a medium, light travels in space

How are sound waves and electromagnetic radiation

similar? How are they different?

$800Frequency times the wavelength

A wave’s velocity is the product of the

$1000

Sound travels through a material medium, and can not travel through a vacuum

Why can you hear a tree fall in the forest but you can’t

hear me slam the space capsule door in space?

$200

Photon

Individual packet of electromagnetic radiation

$400

An analysis of the way atoms absorb and emit light is

Spectroscopy

$600

Kelvin

Temperature scale that places zero at the point where all

atomic motion ceases.

$800

fourth

According to Stefan’s Law: The total energy radiated

by a black body is dependent on the

_______________power of its temperature

$1000

Does diffraction show wave nature or Particle nature of

light?

Wave

$200

6

The distance between two crest is 6 cm and the distance from the median to the top of the

crest is 4 cm. what is the wavelength?

$400

¼ or .25 Hz

A wave has a period of 4 seconds, what is it’s frequency

$600

It’s temperature

The wavelength of an object’s blackbody radiation

is dependent on?

$800Stefan’s

If the sun’s temperature were doubled, it would give off 16X’s

more energy is an example of what law?

$1000

A few bright emission lines

What kind of spectrum would a neon light give us?
