Waves Vibrations and Oscillations

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.

IR, Red, Orange in a typical fire. A pure hydrogen fire however gives off only IR and a barely visible amount of Blue. Metallic salts in the flame will add their own characteristic colors (e.g. sodium: Yellow, copper: Green).

The frequency of a rotating mirror does not affect the speed of light. The speed of light remains constant at approximately 299,792 kilometers per second in a vacuum, regardless of the frequency of the rotating mirror. The frequency of the mirror may affect how quickly or frequently light pulses are reflected, but it does not alter the speed of light itself.

The basilar membrane is most sensitive to very high-frequency sound waves near the base of the cochlea, which is the region closest to the oval window where the vibrations enter the inner ear. This region is characterized by stiff and narrow fibers, which are optimal for detecting high-frequency vibrations.

P-waves, or primary waves, are the fastest seismic waves and typically arrive at the surface first after an earthquake. These waves can travel through both solid and liquid materials, making them the first to be detected by seismographs.

The To and Fro motion about the mean position of any system is known as the vibration or oscillation. Example- A simple pendulum.

Secondary waves, also known as S-waves, are seismic waves that arrive after primary waves (P-waves) during an earthquake. They are slower than P-waves and travel through the Earth by causing particles to move in a perpendicular motion to the direction of wave propagation.

The speed of the movement of the wave through the crust helps to work out the structure of the rocks below the surface of the earth. If the waves move slower the indication is that they are moving through a sedimentary type of rock such as sandstone. If the waves are moving more quickly that would indicate a more crystalline rock like granite..

The air pressure has no effect.

The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude.

That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant.

When calculating the speed of sound, forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height) only because of the changing temperature there.

The de Broglie wavelength formula is given by λ = h / p, where λ is the wavelength, h is Planck's constant, and p is the momentum of the particle. It relates the wavelength of a particle to its momentum, demonstrating the wave-particle duality in quantum mechanics.

The wavelength of a light wave is given by the formula: wavelength = speed of light / frequency. In a vacuum, the speed of light is approximately 3 x 10^8 m/s, which is 300,000,000 m/s. Therefore, the wavelength of a light with a frequency of 40 x 10^14 Hz is 7.5 x 10^-7 m, or 750 nm.

The structure of Earth's interior, including the different layers such as the crust, mantle, and core, was discovered by studying the velocities of seismic waves. The speed at which seismic waves travel through the Earth's layers varies, providing valuable information about the composition and properties of these layers.

Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.
