Q. How are sound waves different from other 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.
Q. What are the different ways sound waves can behave?
Three ways that waves may interact with matter are reflection, refraction, and diffraction.
Q. Do sound waves move like a spring?
The sound travels through the air but not with the air as it moves to your ear. For example, if you listen to someone speaking, the sound travels through the air to your ear but the air from their lungs doesn’t come too. This can be seen with the Slinky — each coil vibrates in place, it does not move along the spring.
Q. What type of energy is visible?
electromagnetic
Q. How many of the electromagnetic waves are visible?
The Visible Spectrum The range of visible wavelengths is 400 to 700 nanometers. Ultraviolet light is the radiation from the sun that causes a sunburn when you have been outside too long on a sunny day.
Q. How do we use visible waves in everyday life?
We concentrate visible light to make lasers to use in everything from surgery, to CD players to laser pointers. Visible light waves also make our TV, computer and cell phone screens work.
Q. Can we see energy waves?
Electromagnetic waves are invisible forms of energy that travel though the universe. However, you can “see” some of the results of this energy. The light that our eyes can see is actually part of the electromagnetic spectrum.
Q. What Colours can humans not see?
Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in the first place.
Q. Do light waves transfer energy?
Light is an example of a wave that transfers energy through empty space.
Q. Does touch transfer energy?
Conduction is heat transfer between two objects that are touching each other. When two objects touch and one has a higher temperature than the other; heat is transferred to the object with the lower temperature. When you touch something hot it feels hot because heat is being transferred from the object to your hand.
Q. Which type of light has the highest energy?
Gamma rays
Q. What type of light travels the fastest?
red
Q. What colors give off positive energy?
Happy colors are bright, warm colors like yellow, orange, pink and red. Pastel colors like peach, light pink or lilac can also have an uplifting effect on your mood. The brighter and lighter a color, the more happy and optimistic it will make you feel.
