s2w1 All about light and spectra

1

Read section 3.1-3.2 in your book - Properties of light and the electromagnetic spectrum. Do you have any questions

1

In visible light, changing the wavelength will change the

1

What are some things people are talking about when the talk about non-visible electromagnetic waves?

1

Waves carry _________ from one place to another

1

Increasing the amplitude of the light changes the light from

1

Define white light

1

The amplitude of a wave tells you how

1

Which of the following is not a mechanical wave?

1

What does it mean that a gas stove produces mostly blue light

1

Read 3.3-3.5 in your book. Any questions?

1

When a blackbody is heated and the light it emits is split, you will see a

1

True or false: Electrons can absorb any amount of energy from visible light

1

true or false: The closer an electron is to the nucleus, the less energy that electron has

1

Suns create what kind of spectra

1

continuous spectra Light moving through a dark cloud of gas will create what kind of spectra

1

A hot cloud of gas that does not qualify as a blackbody will emit what kind of spectra?

1

If the explanations in the book seem a little too dense, these two videos may help. why aren't there green or purple stars
and How do we know what stars are made of

1

A mechanical wave requires a medium. For an ocean wave this medium would be

1

The medium for a sound wave would be

1

All mechanical waves have amplitude, wavelength, period, and wave speed. Look in the area between the arrow to the word elevation and the aline showing amplitude. How many cycles of the wave is show here?

1

c=2.99792458 x 10^8 m/s This is specifically

1

Frequency is the number of full cycles (crest to crest) a wave passes in a second. The unit, a hz, can be converted to what SI unit?

1

Of the following, which carries the most energy?

1

you were given two equations ---> E = hc/ʎ and c= ʎv In both these equations ʎ stands for

1

because c is constant for the speed of light, wavelength and frequency are considered

1

Give a definition for the term blackbody

1

What is the difference between a mechanical wave and electromagnetic wave?
what moves when an electromagnetic wave passes?
What does the Amplitude of the EM wave mean for the light
What does the frequency of the EM wave mean for the light
What does it mean for something to absorb light
what does it mean for an atom to emit light?
what is the relationship between frequency, wavelength, and wave speed?
why are there lines on a spectrum from a sun?
what is a blackbody
What are radio waves, xrays, microwaves etc....

ive got this
I'm fuzzy
so confused
