What is the difference between mechanical waves and electromagnetic waves?

• Mechanical waves are transverse waves, while electromagnetic waves are longitudinal waves

• Mechanical waves can travel at the speed of light, while electromagnetic waves cannot

• Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

• Mechanical waves are produced by electric charges, while electromagnetic waves are produced by vibrating objects

Give an example of a mechanical wave.

• light wave

• heat wave

• sound wave

• radio wave

Give an example of an electromagnetic wave.

What is the difference between analog and digital signals?

• Analog signals are used for audio and video transmission, while digital signals are used for data transmission.

• Analog signals are continuous and can have any value within a range, while digital signals are discrete and can only have specific values.

• Analog signals are more reliable and accurate than digital signals.

• Analog signals are digital representations of physical quantities, while digital signals are representations of abstract data.
