# How are sound and light waves similar and different?

## How are sound and light waves similar and different?

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.

## What is the relationship between sound and light?

Sound travels in waves and exists only within a medium. Light also travels in a wavelike manner but light has electric and magnetic properties and accordingly it is an electromagnetic (EM) wave. Sound travels at 343 m/s in air and light travels through all mediums at almost 300,000,000 m/s.

What are the similarities and differences between light waves and waves in matter?

These are transverse waves, like the ripples in a tank of water. The direction of vibration in the waves is at 90° to the direction that the light travels….How light travels.

Light waves Sound waves
Can they travel through matter (solids, liquids and gases)? Yes (if transparent or translucent) Yes
Can they travel through a vacuum? Yes No

How are light waves and sound waves similar Quizizz?

Only sound waves can have different wavelengths. Only light waves can be reflected. Only sound waves can travel through matter. Only light waves can travel through a vacuum.

### What are the three types of sound waves?

So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Keep reading to find out what qualifies them as such.

### What are the differences between light waves and sound waves quizlet?

Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave. The frequency of a sound wave determines the sound’s pitch, and the amplitude of the sound wave determines the sound’s loudness.

How does light and sound travel in waves?

Sound waves are also different in the sense that they travel through any type of substance, whether solid, liquid or gas, whereas light travels best through empty space. When sound waves hit materials, they cause vibrations. These vibrations are either high frequency or low frequency.

What is the similarities between mechanical and electromagnetic waves?

There are many similarities between light waves and mechanical waves. They can both be measured by their amplitude, wavelength, and frequency. When they interact with matter, they can be reflected, transmitted, absorbed, refracted, or diffracted.

#### How is a light wave created differently than a sound wave?

Light can be considered to be made of waves as well as particles. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.

#### In what medium does light travel the fastest Quizizz?

Light waves travels fastest through the air because air is a gas, which means it is less dense than the other media, which are solids and liquids.

How are sound waves similar to light waves?

The table summarises the similarities and differences between them: Light Sound What type of wave is it? Transverse Longitudinal Can they travel through a vacuum? Yes No. Sound waves can only pass through a Can they be reflected? Yes Yes Can they be refracted? Yes Yes

What are the dissimilarities between light and sound?

There are several dissimilarities between light and sound. Although both are waves, light exhibits particle nature too. Speed of light in air and empty space is a fundamental constant, whereas speed of sound depends heavily on the properties of the medium. The denser the medium, the greater is the speed of sound.

## Why do sound and light waves carry energy?

Sound waves and light waves carry energy that enable you to hear and see the world around you. Write a short paragraph describing water waves you have seen. Science Journal

## What kind of structure is needed for sound to travel?

Presence of atoms, molecules or some structure is necessary for sound to travel; it corresponds to the propagation of a disturbance through a medium. Sound is composed of longitudinal waves (also called compression waves), that is, alternate compressions and expansions of matter parallel to the direction of wave.
