Front

What is the medium in the context of sound travel?

Back

The medium is the substance through which sound waves travel, such as air, water, or solids.

Front

What is kinetic energy in relation to power generation?

Back

Kinetic energy is the energy possessed by an object due to its motion, which can be harnessed to generate electricity in power plants.

Front

Define absorption in wave behavior.

Back

Absorption is the process by which a wave is taken in by an object, resulting in a decrease in the wave's energy.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and cancel each other out, resulting in a reduced amplitude.

Front

What is frequency in wave terminology?

Back

Frequency refers to the number of wavelengths that pass a fixed point in one second, measured in Hertz (Hz).

Front

Explain the concept of wavelength.

Back

Wavelength is the distance between successive crests or troughs of a wave, typically measured in meters.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of a wave when it hits a barrier, while refraction is the bending of a wave as it passes from one medium to another.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to produce a wave with a larger amplitude.

Front

Define amplitude in the context of waves.

Back

Amplitude is the maximum extent of a wave's displacement from its rest position, indicating the wave's energy.

Front

What is the role of a power plant?

Back

A power plant converts various forms of energy into electrical energy for distribution and use.
