Parts of waves
How do you call the highest part of a wave?
Crest
When you look at a straw in a glass of water, it looks broken. What type of interaction is that?
Refraction
Which EM wave properties can vary?
Their wavelength and frequency
What type of waves cause sound?
Mechanical waves
Vibration
Which type of waves from the electromagnetic spectrum can cause skin cancer?
Ultraviolet light waves
How do you call the lowest part of a wave?
Trough
When we see a rainbow in the sky, it is because the light goes through the water droplets of rain. This is an example of which type of interaction?
Refraction
Which is the speed of light?
300,000 km/h
Are sound waves longitudinal or transverse?
Longitudinal
Which are the two types of mechanical waves?
Longitudinal or transverse
How do you call the height of the wave from its resting position to the crest?
amplitude
When we see the color of an object, it is because this is the only one it is reflected, but what happened to the rest of colors that we cannot see?
They are absorbed.
In the electromagnetic spectrum, which type of waves have the second longest wavelength?
Microwaves
Which type of material transmits sound the fastest? (medium)
solids
What type of waves are ocean waves?
Mechanical (transverse)
How do you call the distance of a full wave crest to crest or trough to trough?
Wavelength
When the light waves bend and go around an object, what type of interaction is that?
Diffraction
Which part of the wave makes each color seen differently?
Their different wavelength.
What happens when a sound wave travels from a cold medium to a warmer one?
It will travel faster.
What is a medium?
The material through which a wave travels.
What is frequency?
The amount of waves from a specific distance
What does it mean that a wave can be transmitted?
It means that it can go through an object.
What is the main source of EM waves?
The sun
What happens when the amplitude of a sound wave changes?
Its loudness changes.
In what ways can mechanical waves move that electromagnectic cannot move?
Longitudinal
