Basics of Waves
What are the three properties of waves?
Wavelength, frequency, and amplitude.
Name two types of waves commonly encountered in daily life.
Sound waves and light waves.
Define wavelength
Wavelength is the distance between successive crests of a wave
energy due to motion
Kinetic energy
energy stored in chemical substances
Whats the difference between EM waves and mechanical waves?
electromagnetic waves, like light, can travel through empty space.
What distinguishes sound waves from light waves?
Sound waves require a medium to travel, while light waves can travel through empty space.
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation, including visible light, infrared, ultraviolet, etc.
energy due to position or shape
potential energy
The total kinetic and potential energy associated with the motion and position of an object
mechanical energy
Differentiate between transverse and longitudinal waves.
In transverse waves, particles move perpendicular to the wave's direction, while in longitudinal waves, particles move parallel to the wave's direction.
Describe the motion of particles in transverse and longitudinal waves.
In transverse waves, particles move perpendicular to the wave's direction, while in longitudinal waves, particles move parallel to the wave's direction.
How do sound waves travel through different mediums?
Sound waves travel through solids, liquids, and gases by causing particles in the medium to vibrate.
electrical energy
energy due to electrons
The total energy of the motion in the particles of a substance
thermal energy
Define frequency
frequency is the number of waves passing a point per second.
Give an example of a transverse wave.
Light waves are an example of transverse waves.
What is compression and rarefaction in sound waves?
Compression is when air particles bunch up, creating high-pressure regions, and rarefaction is when air particles spread out, creating low-pressure regions.
energy caused by the vibrations of molecules
sound energy
energy stored in the nucleus of an atom
nuclear energy
Provide examples of real-world applications of light and sound waves.
Medical imaging, communication technologies, music production, and more.
Provide an example of a longitudinal wave.
Sound waves are an example of longitudinal waves.
What is the source for most electromagnetic waves we are exposed to in a day?
The sun
energy carried by light
radiant energy
