Compression and Rarefaction

Compression is a region in a wave where the medium particles are densely packed together. Rarefaction represents a region where the particles of the medium are spread apart.

Half of the vertical distance from the trough to the crest of a wave is its amplitude.

The number of waves that pass a specific point in a given time is called frequency.

Calculate wave speed using the formula: Speed = wavelength × frequency.

Wave speed can be calculated using the formula: Speed = wavelength × frequency.

Mechanical waves require matter to transport energy and cannot transmit energy in a vacuum.

Mechanical waves are waves that cannot transmit energy in a vacuum and require matter to transport.

Electromagnetic waves transmit energy in a vacuum and are transverse waves.

Electromagnetic waves are transverse waves that transmit energy in a vacuum.

Examples of electromagnetic waves include heat and light waves, infrared light waves, radio waves, microwaves, gamma waves, and X-ray waves.

Examples include heat and light waves, infrared light waves, radio waves, microwaves, gamma waves, and X-ray waves.

Pitch refers to the highness or lowness of a sound.

Pitch is the highness or lowness of a sound.

Infrasound refers to sound waves with frequencies below human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above human hearing (above 20 kHz).

The observed change in frequency of a wave when the source or observer is moving is known as the Doppler effect.

The Doppler effect is the observed change in frequency of a wave when the source or observer is moving.

Radiant energy is energy transmitted by electromagnetic waves.

A photon is a particle or bundle of electromagnetic waves that travels at the speed of light (300,000 km/s).

The bouncing back of light when it strikes a smooth surface.

The bending of light rays when it travels from one medium to another.

Difference between convex and concave mirrors

The reflecting surface of the convex mirror bulges outward while the concave mirror bulges inward.

Convex lens and its use

A convex lens is thicker in the middle than at the edge. It is used to magnify objects.

Concave lens and its use

A concave lens is thinner in the middle than at the edge and causes the light to spread out. It is used in optical equipment.

Interference of waves

When two or more light waves meet or overlap, the result is known as interference.

Energy bending between mediums

As wave energy moves from a material with one density through another material with a different density, the waves either speed up or slow down, causing the energy waves to bend.

Prisms and lenses refract light, but most lenses do not cause light components to separate, while prisms do.

Additive primary colors of light

They are called the additive primary colors of light because they can be combined to form all the other light colors.

Sound waves as longitudinal

Sound waves are classified as longitudinal waves because the waves vibrate parallel to the motion of the wave's movement.

Longitudinal waves are also called compression waves.

Because the energy moves as compressions that move parallel to the direction of the wave.

The rush of air could further damage your eardrum.

If the air moved with the sound waves.

Scientists use sonar to measure the distance to an object below the surface.

The time it takes for the sonar wave to bound back is used to calculate the distance to the object.
