Which is greater 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. Speed of light in water = 226 million m/s or 205,600 mph.

Which has more frequency sound or light?

Not only are the light frequencies much higher, but the highest one is only about twice the lowest one. The sound frequencies are much lower, and the highest one is a thousand times higher than the lowest one.

How dense is sound?

Sound energy density or sound density is the sound energy per unit volume. The SI unit of sound energy density is the pascal (Pa), which is 1 kg⋅m−1⋅s−2 in SI base units or 1 joule per cubic metre (J/m3)….Sound energy density.

Sound measurements
Particle velocity	v, SVL
Particle displacement	δ
Sound intensity	I, SIL
Sound power	P, SWL, LWA

Which one has more density of light?

Diamond: the refractive index of diamond is 2.42, that is highest. The optical density is directly dependent on the refractive index. Thus, the diamond is the material that has maximum optical density.

Is light faster than sound Yes or no?

The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. If you have light that’s going through a media, it can travel slower than that.

Which wavelength is greater sound or light?

Sound waves travel a million times slower than light waves. Sound has greater wavelength as compared to the wavelength of light. The wavelength and frequency are closely related whether it is sound or it is light.

Does sound become light?

Under some circumstances, sound can actually form light! It might come as a surprising fact that it is possible to turn sound into light. The phenomena are called “sonoluminescence” whereby a loud sound generates an emission of light.

Does sound depend on density?

The speed of the sound depends on the density and the elasticity of the medium through which it travels. In general, sound travels faster in liquids than in gases and quicker in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

How does density affect sound?

Density. The density of a medium is the second factor that affects the speed of sound. If a material is more dense because its molecules are larger, it will transmit sound slower. Sound waves are made up of kinetic energy.

Does light have density?

If you are talking about mass density, no, light does not have mass so it doesn’t have density.

Which medium has lowest density?

Also, the medium with lowest optical density is air, and its refractive index is minimum (=1.0003).

What is the difference between light and sound?

• Light is a form of electromagnetic wave, whereas sound is a pressure density wave. • Light does not require any medium to travel but sound does require a medium to travel. • Light energy is quantized in packets of energy called photons, but sound energy is a continuous stream of energy on the scale.

How does density affect the velocity of sound and light?

A higher density leads to more elasticity in the medium and hence the ease by which compression and rarefaction can take place. This way the velocity of sound increases by increase in density. Light on the other hand is a transverse electromagnetic wave.

What is the relationship between optical density and light speed?

Optical Density and Light Speed. Refraction is the bending of the path of a light wave as it passes from one material to another material. The refraction occurs at the boundary and is caused by a change in the speed of the light wave upon crossing the boundary.

What is the importance of light energy and sound energy?

The propagations of light energy and sound energy are very important in the survival of the mankind. The study of light energy and sound energy is widely done in fields such as acoustics, LASER technology, electromagnetic theory and various other fields in physics and engineering.
