What do waves tell us?
A medium:
A medium is like the stuff or material that a wave travels through. It could be air, water, or even the ground. Waves need this stuff to move around and make things vibrate. For example, sound waves travel through the air, and seismic waves move through the ground.
Propagation:
Propagation refers to the spreading, transmission, or movement of waves, particles, information, or organisms through different mediums or environments.
A Reflection:
Reflection refers to the bouncing back of waves, particles, or light when they encounter a surface or boundary, changing their direction without changing their properties.
An echo:
An echo is a reflection of sound waves that reach a surface and bounce back, producing a repeated and delayed sound perception.
Tyoes of waves
Seismic waves:
Seismic waves are a type of mechanical waves caused by earthquakes or other sources of ground movement. They travel through the Earth's crust and can be felt or detected by instruments called seismometers. Seismic waves help scientists understand the structure and properties of the Earth's interior.
Mechanical waves:
Mechanical waves are waves that need something to travel through, like air or water. They make the particles in that stuff move back and forth to transfer energy. Examples are sound waves, earthquake waves, and waves in the ocean.
Amplitude:
Amplitude is the measure of a wave's strength or intensity, showing how far its particles move from their usual position.
Frequency:
Frequency means how many times a wave goes up and down in a certain time. It's like counting how often a bouncing ball goes up and down in a minute.
Time period:
Time period is the time it takes for a wave to complete one full up-and-down cycle.
Wavelength
Wavelength is the distance between two similar points in a wave, like from one peak to the next or one trough to the next.
Seismometer:
A seismometer is a scientific instrument used to detect and record the vibrations and movements of the Earth's surface, primarily earthquakes and ground motions.
Interference:
Interference means when two or more things like waves or sounds mix together. Sometimes they make each other stronger, and other times they make each other weaker or disappear.
Constructive interference:
Constructive interference occurs when two or more waves meet and their combined effects result in a larger, more intense wave. This happens when the peaks of the waves line up with each other, adding up their energies.
Destructive interference:
Destructive interference occurs when two or more waves meet and their combined effects result in a smaller or even zero-amplitude wave. This happens when the peaks of one wave align with the troughs of another, causing them to cancel each other out.
Transverse waves:
Transverse waves are waves in which particles move up and down or side to side, while the wave moves forward, like ripples on water or light waves.
Electromagnetic spectrum:
The electromagnetic spectrum is a range of all the different types of electromagnetic waves, including visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, ordered by their wavelengths or frequencies.
Longitudinal waves:
Longitudinal waves are waves in which the particles of the medium move back and forth in the same direction as the wave itself, creating areas of compression and rarefaction. An example of a longitudinal wave is sound, where air particles vibrate along the direction of the sound wave propagation.
What I don't know
Pupil:
The pupil is the black circular opening in the center of the eye that lets light enter. It changes size to control the amount of light reaching the retina, helping us see in different lighting conditions.
Optic Nerve:
The optic nerve is like a cable that connects the eye to the brain. It carries the signals created by light-sensitive cells in the retina to the brain, allowing us to see and perceive the world around us.
Retina
The retina is a layer at the back of the eye that captures light and sends messages to the brain for us to see.
Ear Canal:
The ear canal is like a tunnel that leads from the outside of your ear to your eardrum. Sound travels through this tunnel to reach the middle and inner parts of your ear, allowing you to hear.
Artery:
An artery is a big road in your body that carries the good blood from your heart to all the places that need it to stay healthy and strong.
Aqueous Body:
The aqueous body, also called the aqueous humor, is like a clear liquid cushion inside your eye. It fills the front part of your eye, helping to maintain its shape and providing nutrients to the cornea and lens.
