MECHANICAL WAVES
What are mechanical waves?
Waves that travel through matter.
This is the name for the part of the electromagnetic spectrum that humans can see?
Visiable light waves
This is the form of energy that travels in waves and can be heard by the human ear.
sound energy
What are mediums?
when talking about waves, a medium is the material or substance through which a wave travels.
This type of wave can travel through a vacuum and includes light, radio, and X-rays.
is an electromagnic waves
What are the only mediums mechanical waves can travel through?
Matter
What light wave has the longest wave length and the lowest energy?
Red
This part of the ear vibrates when sound waves hit it.
the eardrum
This is the most common medium through which sound travels on Earth?
Air
This is the only part of the electromagnetic spectrum visible to the human eye.
visble light
Can a mechanical wave exist in space?
No, because they can only travel through matter.
This color of visible light has the shortest wavelength and the highest energy?
violet
This term describes how high or low a sound is, based on its frequency.
is the pitch
This state of matter allows sound to travel faster than in air or water because its particles are packed tightly together?
These waves have the longest wavelength and lowest frequency in the spectrum.
radio waves
How do mechanical waves differ in solids and in liquids
They move differently because liquids only support longituital waves while solides support both
This tool separates white light into its different colors by bending the light wave?
Prism
This unit is used to measure the loudness or intensity of sound.
decibel
Unlike sound waves, these waves can travel through space without needing a medium?
Electromagnetic Waves
This electromagnetic wave type is used in medical imaging to view bones.
x-rays
What are the main types of mechanical waves?
transverse and Longitudinal
This explains why a pencil looks bent when placed in a glass of water, due to light changing speed as it moves between different mediums?
Refraction
This occurs when sound waves bounce off surfaces and return to the source.
is the echo
What are 2 of the waves that can travel through space and don't need a medium?
Light waves, and Electromagnetic waves
This type of electromagnetic wave is used in night vision goggles and remote controls, and it has longer wavelengths than visible light.
