Light energy consists of electromagnetic waves that travel at the speed of light, while sound energy consists of mechanical waves that travel at a much slower speed. Light energy does not require a medium to travel through, whereas sound energy does. Light energy can travel through a vacuum, whereas sound energy cannot.

How does the wave from a loud sound compare to the wave of a soft sound?
A loud sound has a higher amplitude and a greater intensity, resulting in a larger wave with greater energy. In contrast, a soft sound has a smaller amplitude and lower intensity, producing a smaller wave with less energy.
How are contrast radiant energy and sound energy alike?
Contrast radiant energy and sound energy are both forms of energy that can travel through a medium, such as air or water. Contrast radiant energy travels as electromagnetic waves, while sound energy travels as mechanical waves. Both forms of energy can transfer from one object to another.
Can light energy make sound?
No, light energy cannot directly make sound. Sound is produced by the vibration of particles in a medium, while light travels as electromagnetic waves. However, light energy can be converted into other forms of energy that could produce sound indirectly.
Where can light and sound energy be found?
Light energy can be found in sources such as the sun, light bulbs, and candles. Sound energy is produced by vibrating objects such as musical instruments, human voices, and machinery.
What has chemical energy and can be changed into light energy and sound energy?
A battery is an example of something that has chemical energy and can be changed into light energy and sound energy. When a battery powers a flashlight, the chemical energy is converted into light energy, and when it powers a speaker, the chemical energy is converted into sound energy.
