Sound and EM Waves

Front

What are sound waves?

Back

Sound waves are longitudinal waves that travel through a medium (like air, water, or solids) by compressing and rarefying the particles in that medium.

Front

What is the difference between longitudinal and transverse waves?

Back

Longitudinal waves have particle movement parallel to the direction of wave propagation (like sound), while transverse waves have particle movement perpendicular to the direction of wave propagation (like light waves).

Front

What is amplitude in sound waves?

Back

Amplitude is the maximum displacement of particles from their rest position in a wave, which determines the loudness of the sound.

Front

What is frequency in terms of waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means more waves per second.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as from crest to crest or trough to trough.

Front

What type of electromagnetic wave can humans see?

Back

Humans can see visible light, which is a small part of the electromagnetic spectrum.

Front

What happens to sound waves as they travel through different mediums?

Back

Sound waves travel faster in solids than in liquids, and faster in liquids than in gases due to the density and elasticity of the medium.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength decreases, the frequency increases, and vice versa.

Front

What is an x-ray?

Back

X-rays are a type of high-energy electromagnetic radiation that can penetrate soft tissues but are absorbed by denser materials like bones.
