Waves and their Applications

Front

What is the speed of radio waves?

Back

Radio waves travel at the speed of light, which is approximately 186,000 miles per second.

Front

What makes digital recordings more reliable than analog recordings?

Back

Digital recordings do not get corrupted by noise, making them more reliable.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle movement is perpendicular to the direction of wave propagation.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position, and an increase in amplitude is associated with an increase in energy.

Front

What is the difference between digital and analog signals?

Back

Digital signals are composed of precise values that do not vary over time, while analog signals are continuous and can vary.

Front

How do waves transmit energy?

Back

Waves transmit energy through oscillations or vibrations in a medium or through space.

Front

What is frequency in relation to waves?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest.

Front

What is the relationship between frequency and energy?

Back

Generally, an increase in frequency is associated with an increase in energy of the wave.

Front

What is a digital signal?

Back

A digital signal transmits information in discrete values, often represented as binary code.
