# How are mechanical and electromagnetic waves similar and different?

Contents

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. The mechanical waves need a medium like water, air, or anything for it to travel.

## What is the similarities 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 are the similarities and differences between sound waves and electromagnetic waves?

Sound waves are mechanical waves whereas electromagnetic waves are not mechanical waves. Therefore, sound waves require a medium for their propagation whereas electromagnetic waves do not require a medium. This is the main difference between sound waves and electromagnetic waves.

## How are waves similar and different?

2 Answers. For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.

## What is the difference between mechanical and electromagnetic waves for kids?

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 is the difference between a mechanical wave and an electromagnetic wave quizlet?

A mechanical wave has a high frequency, while all electromagnetic waves have low frequencies. A mechanical wave travels through matter, while an electromagnetic wave travels through empty space. A mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

## How are electromagnetic waves different from all other waves?

Electromagnetic waves differ from all other waves in two primary ways. They travel in small discrete packets, and they are the only type of wave that can propagate through a vacuum. … The other types of waves such as water, seismic, and sound waves do not have a particle-like nature to them.

## What are the similarities between electromagnetic waves and sound waves?

Both kinds of waves carry energy from one place to another and have a wavelength, frequency and velocity. The velocity of sound waves is much lower than that of electromagnetic waves.

## What is one thing that EM waves and sound waves have in common?

Unlike water waves, electromagnetic waves always travel at the same speed (3 hundred million metres per second) and sound waves all travel at the same speed in a given medium (for example, approximately 340 metres per second in air). The speed of a wave is related to both its frequency and wavelength.

## What is one main difference between sound waves and electromagnetic waves?

What are the differences between sound waves and electromagnetic waves? Propogation: Sound waves are longitudinal, meaning that the vibrations occur parallel to the direction of propogation (travel). Electromagnetic waves are transverse, meaning that the vibrations occur perpendicular to the direction of propogation.

## What are the differences and similarities of a compression wave and a transverse wave?

In the longitudinal wave, the medium moves left to right, while in thee transverse wave, the medium moves vertically up and down. Longitudinal waves have a compression and rarefaction, while the transverse wave has a crest and a trough. Longitudinal waves have a pressure variation, transverse waves don’t.

## What similarities do all waves share?

All electromagnetic waves:

• are transverse waves;
• can travel through a vacuum ;
• travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.

## How are electromagnetic waves are different than mechanical waves select all that apply?

Electromagnetic waves carry energy through a medium; mechanical waves carry energy through media and space. Mechanical waves carry energy through a medium; electromagnetic waves carry energy through media and space.

## What is mechanical waves and electromagnetic waves?

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. … In contrast, electromagnetic waves require no medium, but can still travel through one.

## How are electromagnetic waves different from mechanical waves Brainpop?

How are electromagnetic waves different from mechanical waves? Electromagnetic waves can travel through empty space; mechanical waves can’t.
