Does light behave in a predictable way?

Do light waves behave in a predictable way?

Waves interact with materials. … When waves interact with materials in these ways, they behave predictably. All waves, from water waves to sound waves and even light waves, show the behaviors that you will learn about next. Scientists call these behaviors reflection, refraction, and diffraction.

Which is faster light or sound?

The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space. … Speed of light in a vacuum and air = 300 million m/s or 273,400 mph.

What type of light can humans not see?

Wavelengths of light are measured in nanometers (nm). One nanometer is a billionth of a meter. Visible light has wavelengths ranging from about 400 nanometers to 700 nanometers. Wavelengths shorter than 400 nm, or longer than 700 nm, are invisible to the human eye.

What is an example of sound reflection?

It is the sound heard when reflections occur from a firm surface, for example, a wall or cliff. Echo is the repetition of sound even after the source has stopped vibrating. This is used by bats as well as dolphins for the detection of obstacles or navigation.

Is light a wave or a particle?

Light Is Also a Particle!

Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein’s light quantum theory is that light’s energy is related to its oscillation frequency.

Do waves carry matter?

It is important to remember that all waves transfer energy but they do not transfer matter .
