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 is the relationship between light and sound Why do light and sound travel in different rates?
Light waves travel much faster than sound waves
. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. (Actual speeds are on the 2
nd
page)
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.
Is sound a form of 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.
Can light and sound reflect?
Sound waves and light waves
reflect from surfaces
. The angle of incidence equals the angle of reflection .
Which color has the lowest amount of energy and why?
Red is the lowest energy visible
light and violet is the highest. A solid object has color depending on the light it reflects. If it absorbs light in the red and yellow region of the spectrum, it will have a blue color.
Can light travel through a vacuum?
Light can travel in a vacuum
.
A vacuum is empty space. There are no molecules of air or anything else in a vacuum. Like all forms of electromagnetic waves, light can travel through empty space, as well as through matter.
Why are light and sound not considered as matter?
Light and sound are not considered as a matter, because
it have not mass,weight, volume and doesn't occupies space and not have area
. It is non visible.
How many times faster is light than sound?
The standard metric for the speed of light is that of light traveling in vacuum. This constant, known as c, is roughly 186,000 miles per second, or roughly
one million times the speed
of sound in air.
Is anything faster than light?
Albert Einstein's special theory of relativity famously dictates that
no known object can travel faster than the speed of light in vacuum
, which is 299,792 km/s. … Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.
Which comes first sound or light?
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. … No information can propagate faster than the speed of light.
Can a person see sound?
Synesthesia
is a condition where the brain mixes up the senses— and one sensory modality causes a simultaneous stimulation of another. For example, a person with synesthesia may “hear color” or “see sound.”
Do light waves make sound?
The waves themselves don't usually produce sound
, but their effect on other objects (particularly ferromagnetic ones) can be audible. This is similar to how speakers work (except they use magnetic fields, not waves).
Why is light and sound important?
One of the most important facts to understand about both light and sound is that
both are forms of energy that move in 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.
Can light bounce off sound?
Q: In any way can sound reflect light or vice verse? …
Yes
, sound waves change the density (or more generally, refractive index) of the material they're traveling in. Light waves diffract off that varying index of refraction.
What law of reflection of light is applicable to sound as well?
Sound propagates through air as a longitudinal wave. … The law for reflection is the same as that of light, ie., the
angle of incidence of a sound wave
equals the angle of reflection, just as if it were produced by a ‘mirror image' of the stimulus on the opposite side of the surface.
