Wave anatomy
What is the highest point of a transverse wave called?
Crest
Sound travels as a:
Longitudinal wave
Which type of electromagnetic wave has the highest frequency (most energy)?
Gamma Rays
What cells in the eye help us see color?
Cones
A student sees lightning before hearing thunder. Why?
Light travels faster than sound
What is the distance from one crest to the next crest called?
Wavelength
What general type of waves need a medium to travel through?
Mechanical waves
These Rays are used for night vision cameras
Infrared
Which color of visible light has the most energy?
Violet
If a wave's amplitude increases, what also increases?
Its energy
What does the amplitude of a wave measure?
The height from rest to crest
What general type of wave does not need a medium to travel through?
Electromagnetic waves
What part of the electromagnetic spectrum can humans see?
Visible light
Combining red, green, and blue lights makes what type of light?
White light
What happens to the energy of a wave if the frequency increases?
It increases
In a longitudinal wave, the part where the particles are closest together is called a:
Compression
A wave moves through a rope. The rope moves up and down, but the wave moves left to right. This is an example of a:
Transverse wave
These are the lowest energy electromagnetic waves.
Radiowaves
If I shine a red light on a blue shirt what color will the shirt appear?
Black
Blue shirt reflects blue light and absorbs red and green light.
You only transmitted red light, so no light will be reflected.
If you shine only red and green light on a white wall, the wall will appear:
Yellow
A wave length times its frequency is:
It's speed
A mouth piece of a trumpet vibrates and makes sound. The vibration is a _____ wave, and the sound is a _____ wave.
Transverse, longitudinal
These waves are used in wireless communication like cell phones and Wi-Fi.
