# How are light and sound similar?

## How are light and sound similar?

Comparing light and sound waves

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 solid, liquid or gas.
Can they be reflected? Yes Yes
Can they be refracted? Yes Yes

What are three similarities between light and sound waves?

Similarities

• light waves and sound waves can both be diffracted, reflected & refracted.
• they can both have a range of frequencies and wavelengths.
• they both transfer energy without transferring matter.

### Is light and sound the same thing?

The differences between light and sound are as follows: Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum.

Does light function in the same way as sound waves?

While they are both forms of energy that travel in the form of waves, there are vital differences between sound waves and light waves. Sound and light travel at significantly different speeds. Light waves move at speeds that are nearly one million times faster than sound waves are capable of traveling.

#### Is light faster than sound?

The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space. Speed of light in water = 226 million m/s or 205,600 mph.

Can light be heard?

The emitted light intensity fluctuates in synchrony with each half wave of the AC supply and creates a photoacoustic signal with twice the line frequency. Depending on where the experimenter lives, a tone with 100 Hz or 120 Hz can be heard.

## What are 2 similarities between light and sound waves?

Light and sound are both waves. The propagation, or distribution of sound, is actually very similar to light, just a whole lot slower. The waves of sound or light both reflect, refract, and attenuate depending on their environment.

Which is faster light or sound?

The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Speed of light in a vacuum and air = 300 million m/s or 273,400 mph.

### Does light make sound?

Light does not, except very indirectly, make sound. The two things are about as different as can be, despite both bearing similar tags of “vibration” and “wave” and “energy carrier”. High power laser radiation can cause electric breakdown in the air, the breakdown produces sound.

What is faster light or sound?

#### What speed does light travel in a vacuum?

Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the “vacuum” of empty space.

What is the fastest thing ever?

Laser beams
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

## What are the similarities between sound and light?

There are three basic similarities between sound waves and light waves including interference, diffraction and refraction. Both the waves have the property of interference. When two coherent waves of sound waves or light waves fall in a same medium in a same direction, interference takes place.

Why is light faster than sound?

Light travels faster than sound because sound waves can only travel as waves of pressure in a medium,whereas electromagnetic waves,of which light is made, move on their own even through vacuum.

### Does sound travel faster than light?

Under normal conditions, light moves roughly a million times faster than sound, but under the right conditions sound can travel faster than light . The reason sound typically travels slower than light is because light naturally travels (in a true vacuum) at the fastest possible speed information can travel (light speed).

Which moves faster light or sound?

Light travels faster than sound. Light travels at 299,792,458 metres per second and sound only travels at about 343 metres per second.
