Which are characteristics of a ray when it hits a boundary and refracts but not?
F. Only these two options are characteristics of a ray when it is refracted, but not when it is reflected. In fact: Reflection occurs when a ray hits the interface between two mediums and bounces off back. When it is reflected, the ray changes direction, but does not change speed since it does not change medium.
What happens to light rays when they hit a boundary?
Glass is denser than air, so a light ray passing from air into glass slows down. If the ray meets the boundary at an angle to the normal , it bends towards the normal. The reverse is also true. A light ray speeds up as it passes from glass into air, and bends away from the normal by the same angle.
What is a boundary behavior?
The behavior of a wave (or pulse) upon reaching the end of a medium is referred to as boundary behavior. When one medium ends, another medium begins; the interface of the two media is referred to as the boundary and the behavior of a wave at that boundary is described as its boundary behavior.
What happens when lights hit a boundary?
A light wave transports energy from one location to another. When a light wave strikes a boundary between two distinct media, a portion of the energy will be transmitted into the new medium and a portion of the energy will be reflected off the boundary and stay within the original medium.
What happens to a wave when it encounters a boundary?
When a wave encounters a boundary which is neither rigid (hard) nor free (soft) but instead somewhere in between, part of the wave is reflected from the boundary and part of the wave is transmitted across the boundary.
What are the typical wave behaviors?
Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.
What does a wave transfer from one place to another?
A is a disturbance that transfers energy from one place to another. Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance.
Which of the following is an example of mechanical wave?
Some of the most common examples of mechanical waves are water waves, sound waves, and seismic waves.
What are three examples of waves?
Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.
