What are sound waves with frequencies below normal range?
Sound waves with frequencies below the normal range are called infrasound. These waves have frequencies lower than 20 Hz, which is typically the lower limit of human hearing. Infrasound can be created by natural phenomena such as earthquakes or by man-made sources like industrial machinery.
Sound waves with frequencies higher than 20000 Hz are referred to as subsonic waves?
for this answer it's false i made a 90 on this test :)
What is the composition of the spectrum that is made up of different waves?
The spectrum is composed of different waves with varying wavelengths and frequencies.
What are sounds called with frequencies below 20 Hz?
Sounds with frequencies below 20 Hz are called infrasound. These low-frequency waves are below the range of human hearing but can still be felt by the body. Infrasound is produced by natural events like earthquakes and weather phenomena, as well as man-made sources like machinery and explosions.
What makes up the electromagnetic spectrum and how is it classified?
The electromagnetic spectrum is made up of different types of electromagnetic waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. These waves are classified based on their wavelength and frequency, with longer wavelengths and lower frequencies at one end (radio waves) and shorter wavelengths and higher frequencies at the other end (gamma rays).

What are sound waves called that are trapped or unable to move any further?
In audio we know the word "bass trap". Bass traps are acoustic absorbers which damp low frequencies to attain flatter low frequency room responses. They are turning sound energy into heat through friction. Possibly you think that standing waves are unable to move. The air appears to vibrate in segments or regions and the fact that these vibrations are made up of traveling waves is not apparent - hence the term "standing wave".
What causes colour?
Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.

Waves made by vibrating charges that can travEl without a medium are called?
Electromagnetic waves.
Do sound waves reflect in the same way as light waves?
The properties of waves are the same for all sorts of waves. If sound waves reflect it is called an echo. When light waves reflect it is simply called a reflection. Waves on the ocean can also reflect if they run into a cliff instead of a sandy beach. Reflected waves often cause what are called standing waves where waves travelling in opposite directions reinforce each other and cancel each other out. One point of the wave will hardly move and another point will move up and down double the distance it would if there is only one wave. This is very dangerous for boats. Light also can be made to create standing waves. In radio, antennas must be adjusted to get a Standing Wave Ratio of 1:1 so it works for electrical waves in a wire as well. In live concerts, standing waves can mean real trouble for the sound engineers trying to balance the reflected waves from the back of the hall or auditorium. It is often better to have such concerts outside to avoid such problems.
What made sound?
It was made by air vibrating called sound waves

Do people use the Morse code today?
Yes, but almost completely as a hobby (ham radio).A2. For communicating with submerged submarines, use is made of Very Low Frequencies,
What is the reason that surface waves usually cause the most damage?
Surface waves usually cause the most damage because they have a horizontal motion that can shake the ground violently, leading to widespread destruction of buildings, roads, and infrastructure. Additionally, surface waves travel slower than other seismic waves, allowing more time for the shaking to cause damage.
