Waves Vibrations and Oscillations

The vibration of the Longitudinal wave is parallel to the wave direction and the vibration is perpendicular to the direction in the transverse wave.

The electromagnetic wave used to send signals in satellites is called radio waves. These waves have long wavelengths and are able to travel long distances through space without the need for a physical medium.

Yes, stars produce electromagnetic waves as a result of nuclear fusion reactions in their cores. The energy released during these reactions causes the stars to emit electromagnetic radiation across various wavelengths, including visible light, ultraviolet light, and X-rays.

For polarization the direction of the oscillation has to be perpendicular to the direction of travel. In sound waves, which are longitudinal waves, this isn't the case and thereby can not be polarized.

Sound waves are made up of longitudinal waves. This means that the particles of the medium in which the sound is moving vibrate parallel to the direction of the wave.

The frequency of the wave multiplied by the wavelength equals the speed of light. The speed of light, abbreviated "c", is 186,000 miles per second or 300,000 km per second. This is a constant.

What's more, according to Einstein's theories of relativity, the is invariant (doesn't change) across all frames of reference.

There are three Lewis resonance structures for the SO3 2- ion. This is because sulfur can form multiple double bonds with the oxygen atoms, resulting in different arrangements of the double bonds and lone pairs.

The wavelength of a wave is calculated using the formula: wavelength = speed of sound / frequency. Substituting the values given: wavelength = 1530 m/s / 7 Hz ≈ 218.57 meters. Therefore, the wavelength of the T Wave is approximately 218.57 meters.

A stretched-out area of a wave is called a rarefaction.

People can typically hear sound waves with frequencies ranging from 20 Hz to 20,000 Hz. Frequencies below this range are infrasound (below 20 Hz), and frequencies above this range are ultrasound (above 20,000 Hz).

No. All sound waves in the same air move at almost exactly the same speed.

If different frequencies moved at different speeds, then live orchestras, choruses,

and bands would be impossible ... sounds from different instruments or voices

would reach the audience in the seats at different times. It would be a mess.

Radio waves have wavelengths that can vary from hundreds of meters to as small as a few millimeters. For a typical adult human, who is around 1.7 meters tall, the closest match in terms of wavelength would likely be in the lower frequency range of radio waves, such as Medium Frequency (MF) or Long Wave (LW) radio waves.

Heat waves are not a type of wave like sound or light waves. They refer to extended periods of excessively hot weather, often accompanied by high humidity, which can have various negative effects on human health and the environment.

Yes!

All sound waves, regardless of pitch move at the same speed provided they are in the same medium. Differences in frequency cause the sound to be perceived as higher or lower. A high pitched sound has a higher frequency and shorter wavelength while low pitched sounds have lower frequencies and longer wavelengths

Transverse and Compressional electromagetic waves

Another opinion:

No electromagnetic waves are compressional waves. They're all transverse.

I think what the question was looking for is:

-- Heat and visible light

-- Radio waves and X-rays

-- Ultraviolet and gamma rays

etc.

• low frequencies induce eddy currents in metals, heating them.
• high frequencies vibrate atoms themselves, heating the material
• higher frequencies trigger chemical changes.
• very high frequencies knock electrons out of atoms, creating reactive ions.

No, all types of electromagnetic waves travel at the speed of light in a vacuum, which is approximately 3.00 x 10^8 meters per second. The speed of light remains constant regardless of the frequency or wavelength of the electromagnetic wave.

The most familiar kind of surface wave is an ocean wave, which is caused by the wind transferring energy to the water's surface. These waves can vary greatly in size and strength, depending on factors such as wind speed and duration.

Yes, the speed of light decreases when entering a different medium such as water compared to its speed in a vacuum. This is due to the change in the refractive index of the medium, which affects the speed at which light can travel.

Yes, a pendulum can vibrate in an artificial satellite since motion in a satellite is relative and independent of gravity. However, because artificial satellites are typically in a state of free fall or orbit around a celestial body, the motion of a pendulum may appear more complex due to the satellite's acceleration and movement.

No, surface waves are typically the last seismic waves to arrive at a seismic facility. They travel more slowly than body waves (P and S waves) and arrive after the initial shaking caused by the faster body waves.

Seeing as nobody has answered I will.

Im not entirely sure so double check with a physics teacher but

once its absorbed the fabric slightly heats up. like 0.0005 degrees.

When absorbed reflection of sound is prevented.

It depends on the context. In terms of light, shorter wavelengths (higher frequencies) have more energy, while longer wavelengths (lower frequencies) have lower energy. In terms of sound, shorter wavelengths (higher frequencies) are perceived as higher pitched, while longer wavelengths (lower frequencies) are perceived as lower pitched.
