What are two similarities and one difference between mechanical waves and electromagnetic waves?

Unlike mechanical waves, which require matter, electromagnetic waves can travel through empty space, as well as through liquids, solids, and gases. There are many similarities between light waves and mechanical waves. They can both be measured by their amplitude, wavelength, and frequency.

What is the main difference between digital and mechanical waves?

In very simple words, an electronic wave is that which travels in a vacuum, and a mechanical wave is that which needs some medium for traveling. Summary: 1. Electromagnetic waves travel in a vacuum whereas mechanical waves do not.

What is the major 3 differences between mechanical waves and electromagnetic waves?

A mechanical wave can be of three types, longitudinal, transverse, and surface waves whereas an electromagnetic wave can only be a transverse wave. An example of a mechanical wave is ripples in a water body whereas those of an electromagnetic wave are microwaves, radio waves, and ultraviolet rays.

What is difference between compression and rarefaction?

A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart. The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction.

What are two differences between mechanical waves and electromagnetic waves?

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. Electromagnetic waves travel at the speed of light but mechanical waves are far slower. Electromagnetic waves are called a disturbance, and mechanical waves are known as a periodic disturbance.

What is the difference between compression and a rarefaction in a longitudinal wave?

Longitudinal waves show areas of compression and rarefaction : compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to particles being spread further apart.

What is the difference between a compression and a rarefaction in a sound wave Illustrate your answer with a sketch?

Compressions in a sound wave occur when the distance between each particle is very less and they are closest to each other so that high pressure is created in the region whereas rarefactions in a sound wave occur when the particles are far away and the distance between them is large so as to create low pressure in the …

What is the difference between mechanical and electromagnetic waves give an example of each?

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.

What do you understand by radiation?

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

What is the difference between electromagnetic radiation and electromagnetic spectrum?

Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum. The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.
