What is the frequncey of a wave?
Frequency of the wave is the number of crests passing at a point in one second. Actually crests are not passing through, but it appears so.
Is frequency of a sound wave defined as the amount of energy passing through a unit area of the wave front in a unit of time?
The _______ of a sound wave is defined as the amount of energy passing through a unit area of the wave front in a unit of time. Correct answer=frequency
What is visible evidence of energy passing through the water?
A wave is visible evidence.
When there are more wave passing through the reference point in a period of timewhich wave characteristics also increase?
The frequency increases.
What happens to an electromagnetic wave when if hits a transparent obstacle?
The wave will pass through the transperent object

When a wave is passing through a uniform medium and the frequency of this wave increases it wavelength does what?
The wavelength gets longer.
When there are more waves passing through the reference point in a period of time which wave characteristic also increases?
when there are more waves passing through the reference point in a period of time, which wave characteristic also increase

What is light refraction for kids?
the bending of light when passing through an object
What color will light appear after passing through a pink filter and hitting a blue object?
Purple will the object be
How do colored filters change the color of an object?
They prevent certain wavelengths (i.e. colours) from passing through. This means that you only see the colours that do pass through. If the object itself is coloured this may result in it becoming invisible if the filter is one that stops the object's colour from passing through it.
What wave that travels through matter produced by a vibrating object?
sound.
