How are light energy and sound energy alike and different?
They can both be analyzed as waves, but light is also a particle phenomenon. Sound must have a medium through which to travel; no medium, no sound. Light needs no medium through which to travel. Our experience of both sound and light can change by what is called the Doppler Effect; the frequency of the waves depends on the movement of the source relative to the observer. However, the waves of light themselves are always moving at c (in a vacuum) regardless of the movement of the source relative to the observer. Sound waves, on the other hand, do change speed depending on the relative movements of the source and observer. If the observer is moving through the air at a given velocity, some fraction of that velocity might be added to or subracted from the velocity of the observed sound.
Is sound faster than the eyesight?
No, sound is not faster than eyesight. Light travels faster than sound, with light moving at approximately 299,792 kilometers per second in a vacuum, compared to sound traveling at 343 meters per second in the air at room temperature.
Can you List 3 things that is faster than the speed of sound?
Light travels much faster than the speed of sound. Some high-speed aircraft can travel faster than the speed of sound, reaching supersonic speeds. Particle accelerators can propel particles to speeds faster than the speed of sound.
What are 3 similarities in light waves and sound waves?
Both light waves and sound waves are forms of energy that travel in waves, they can be reflected, refracted and diffracted. Both can also exhibit properties like interference and polarization.
What are the 3 ways percussion instruments?
Percussion instruments produce sound by being struck, shaken, or rubbed. Each method gives a different tone and quality to the sound produced by the instrument.
How many ways are there to spell the word there?
There are 3 homophones (sound-alike words):there - existence, or location (not here)their - possessive form of them and theythey're - contraction for "they are"
How are common and decimal fractions alike and different?
They are not alike, they are different, but they can be identical in value. Example :- 3/4 and 0.75 are different ways of expressing the same quantity and they are not alike at all.
Is light or sound faster?
Light is faster than sound.
What are 3 other forms of energy?
Speed, Light, Sound
What are 3 energy forms?
sound,light,heat,kinetic(movment)
What 3 types of energy can be created by elctricity?
*thermal *light *sound
What is the speed of light times the speed of sound?
light . . . 3 x 108 m/s sound . . . 343 m/s light-speed x sound-speed = 102,900,000,000 meters2/second2 This quantity has no physical meaning or application.

What are 3 catigories of waves?
water waves, light waves, and sound waves
State five things that you know about sound?
1 sound can be loud 2 sound can be soft 3 there are many different types of sound 4 many things make sound 5 sound is made in different ways
How dowe now light is fster than sound?
The speed of light is 3*108 meters per second. The speed of sound I believe is 330 m/s. Light is actually electromagnetic radiation whereas sound waves are actually pressure disturbances in the air.
What are 3 things that travel in waves even through space?
Radio, light, and sound.
