What is the root word of disturbance?
What is the root word of disturbance?
disturbance (n.) late 13c., “mental distress, emotional disorder of the mind, grief,” from Old French destorbance (12c., Old North French distorbance), from destourber, from Latin disturbare “throw into disorder,” from dis- “completely” (see dis-) + turbare “to disorder, disturb,” from turba “turmoil” (see turbid).
What is called wave?
Mechanical waves, such as sound, require a medium through which to travel, while electromagnetic waves (see electromagnetic radiation) do not require a medium and can be propagated through a vacuum. Propagation of a wave through a medium depends on the medium’s properties. See also seismic wave.
Can we predict the behavior of sound How?
Answer: Yes. Sound travels in air or airwaves thats why we have sound waves. So through the wheather we can predict the behavior of sound.
What is the behavior of light?
Light behaves as a wave – it undergoes reflection, refraction, and diffraction just like any wave would. Yet there is still more reason to believe in the wavelike nature of light.
Can we predict the behavior of light?
Photons are particles of light. But they do not behave like macroscopic particles. We cannot use the laws of classical physics to predict the behavior of individual photons. Quantum mechanics often makes probabilistic predictions. The probabilities can be calculated using a wave equation.
How does each property help us to see things?
Answer: Rays of light reflect, or bounce off, objects just like a ball bounces on the ground. This reflection of light is what enables us to see everything around us. Light can reflect in different ways, changing the way objects look.
What happens to light as it passes through a prism?
Upon passage through the prism, the white light is separated into its component colors – red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.
Why do we refer to light as a wave?
Einstein believed light is a particle (photon) and the flow of photons is a wave. The various properties of light, which is a type of electromagnetic wave, are due to the behavior of extremely small particles called photons that are invisible to the naked eye.
What is the evidence that light is a wave?
In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits. The bright and dark bands demonstrated that the slits were causing light waves to interfere with each other.
What are the two sources of light?
There are two basic types of light sources: Incandescence and Luminescence.
