Waves Flashcards
What is the difference between light and sound waves?
Light is faster, sound is vibrations of particles, sound can’t travel in a vacuum, light is vibrations of electric and magnetic fields (an electromagnetic wave)
What are the similarities of light and sound waves?
They both can reflect and refract, both are made by vibrations, both can transfer energy and information
What are waves
A method to transfer energy but it DOESN’T transfer the material, only the energy
What is a longitudinal wave
Waves where the medium( material or matter) vibrates in the same direction the wave travels in
What is a transverse wave
Waves where the medium( material or matter) vibrates perpendicular to the direction the wave travels in
What are some examples of longitudinal waves
Sound, pressure, shock, slinky toy
What are some examples of transverse waves
Light, water, rope, electromagnetic radiation
What is the wave’s peak
The highest part of the wave
What is the trough of the wave
The lowest part of the wave
What is the amplitude of the wave
The peak or trough to the ‘middle’ of the wave
What is the wavelength of the wave
The length of peak to peak or trough to trough
