Which is true about sound and light waves?
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. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.
Answer and Explanation: Light and sound waves are similar -in that they both have an amplitude, a wavelength, a period and a frequency.
Both light and sound waves need matter to carry energy from one place to another. Neither light nor sound waves need matter to carry energy from one place to another. Light waves carry energy parallel to the motion of the wave, while sound waves carry energy perpendicular to it.
Explanation: Both sound and light waves transmit energy. All waves are a disturbance that move through space and time transferring energy. energy.
Sound waves and light waves carry energy that enable you to hear and see the world around you.
Light waves are transverse in nature and do not require a medium to travel hence they can travel in vacuum. Sound waves are longitudinal waves and require a medium to travel. They do not travel in vacuum.
Different waves, same properties
These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
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.
Note: Similar to light, sound also reflects, refracts and attenuates. The intensity of both sound and light decreases as we move away from the source. Both light and sound are waves but light waves are transverse and sound waves are longitudinal.
Here are some fun facts about sound to get you started! Sound travels much slower than light, whether in the air or in water. Light travels at 186,000 miles per second, whilst sound travels at 770 miles per hour. You often hear things after you see them - for example, you see the lightning before you hear the thunder!
What is common between waves and light waves?
Sound wave and light waves both shows interference.
Sound Waves are longitudinal waves while Light waves are transverse waves. Sound waves always require a medium to travel, that is, they cannot travel in vacuum, while light waves do not require any material medium since they are electromagnetic waves.
These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
TRUE - A sound wave transports its energy by means of particle interaction. A sound wave cannot travel through a vacuum. This makes sound a mechanical wave.
