What is absorption?
When one wave comes into contact with another.
When a wave oscillates in a particular direction.
....in wave motion is the transfer of the energy of a wave to matter as the wave passes through it.
What is diffraction?
A change in direction of a wave as it passes from one medium to another.
Waves which travel through a medium.
The spreading out of waves as they pass through an aperture or around objects.
When would diffraction of sound waves not be good?
If you were at a concert and chose a poor seat behind a post.
If you were at a concert and had no obstacles preventing the sound from reaching you.
What happens when you are color blind?
You cannot see anything and DO NOT see light.
Radio waves between 3 and 30 megahertz (MHz).
Your eyes do not see color the way they should. It can happen when one or more of the color cone cells are absent, not working, or detect a different color than normal.
What is the Electromagnetic Spectrum?
the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
the term used by scientists to describe the entire range of light that exists. EM radiation is classified into types according to the frequency of the wave: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period
What are infrared rays?
They are a type of electromagnetic radiation (a wave with electricity) . The wave is longer than light which humans can see and shorter than microwaves.
They are electromagnetic waves of high energy and very short wavelength, which is able to pass through many materials opaque to light
What are compressions?
a region in a longitudinal wave where the particles are furthest apart.
a region in a longitudinal wave where the particles are closest together.
Which is not true about sound waves?
They travel as vibrating particles, or waves.
The waves are reflected by surfaces.
They are not produced my vibrations.
They propagates as mechanical waves, through mediums such as air or water.
When would diffraction of sound waves not be good?
If you were at a concert and chose a poor seat behind a post.
If you were at a concert and had no obstacles preventing the sound from reaching you.
Which Ultra violet rays plays the greatest role in causing skin cancers?
The UVA rays that penetrate the skin deeply.
The UVB rays which produce sunburn.
What does an incident ray do?
It is a two-dimensional surface, any two of whose points can be joined by a straight line that lies entirely in the surface
It is a wave that move away from the boundary.
It is a ray of light that hits a surface.
True or false? ¿Cierto o falso?
X-rays have much higher energy and much shorter wavelengths than ultraviolet light.
true/cierto
False/falso
How are waves in the ocean usually formed?
In most cases, they are created by volcanic eruptions under the ocean.
In most cases they are created by wind blowing over the surface of the ocean
In most cases, they are created by boats on the ocean.
Where would the equilibrium of a wave be located?
It is the energy of the wave.
It is the length og the wave.
It is the horizontal line in the middle of the wave.
