Chemistry- Ch6: Wave Mechanics

In a wave the top part is called the?

crest

In a wave the middle to top is called the?

amplitude

In a wave the bottom part is called the?

trough

In a wave the horizontal line is called the?

equilibrium

In a wave the wavelength is the?

point on the wave to the next similar point which is the distance in meters

If a uniform wave is shown, the amplitude between the origin and the trough & the origin and the crest will be?

identical

If you start from the crest and go

L→ R, what is happening to the wave?

it is going down from the crest to go to the next point which is the other crest

If you are looking at light the amplitude is how?

bright it is

If you are looking at sound, the amplitude is how?

loud it is

How do you read how many waves u got?

you count how many times it goes up the origin

The number of waves that pass per second is?

frequency

anything you put over time is the?

rate (EX: miles/hr)

In a standing wave, the red dots are?

nodes

As the standing wave goes up and down the nodes?

don't move so it’s the point in which the wave doesn’t go up or down

Nodes are a place of 0?

amplitude so no high or low

waves move?

energy

Electromagnetic spectrum

a series of waves that carry energy

Why does ultraviolet cause cancer?

carries enough energy to mess up and break cells in our body

Gamma rays are?

pure energy

Infared allows you to?

to look at heat patterns and illuminates it (EX: night goggles)

In visible light range, red and violet are?

red is the lowest energy and violet highest energy

Microwaves and AM radio’s are in the?

lower energy of visible light

One side of red and violet is?

one side of red is Infared and violet is ultraviolet which is more in terms of energy

When you shine light to a prism you get a?

continuous spectrum which means you see the entire rainbow
