How does light travel when the medium it travels through changes and how does light travel when the medium does not change?
Light travels in straight lines when the medium's density is constant.
When light enters a different density perpendicularly, it also travels in a straight line.
When light enters a higher density at an angle, it bends towards an imaginary line perpendicular to its pont of entry.
When light enters a lower density medium, it bends away from the imaginary perpendicular line. This is seen with objects partially submerged in water. The light exits the water and bends away from its normal path, making the object appear crooked in relation to the unsubmerged portion.
Sometimes light will be reflected at the boundary of two mediums. This is seen in optic fibres.

The frequency of electromagnetic energy traveling through a medium can change if what changes?
The frequency of electromagnetic energy traveling through a medium can change if the medium's refractive index changes. This can occur when light travels from one medium to another, causing a change in the speed of light, which in turn affects the frequency of the light waves.
How does sound bending occur when there are changes in the medium through which the sound travels?
Sound bending occurs when there are changes in the medium through which the sound travels because the speed of sound varies depending on the properties of the medium. When sound waves encounter a change in medium, such as going from air to water or passing through different temperatures, they can bend or change direction due to the difference in speed. This bending is known as refraction and can cause sound to be heard differently than expected.
What happens when a wave travels from one medium to another in refraction?
When a wave travels from one medium to another in refraction, it changes direction and speed due to the change in the medium's density. The wave's frequency remains the same, but its wavelength changes as it enters the new medium.
In Waves Workbook Module 5, Exercise 10a, how does the wavelength change in the grey medium?
In Waves Workbook Module 5, Exercise 10a, the wavelength changes in the grey medium by decreasing as it travels through the medium.
Sound travels as a what?
Sound travels as a wave through a medium, such as air, water, or solids. The vibrations of particles in the medium create pressure changes that propagate as sound waves.
A medium can effect speed of sound by changes in what?
When you change density and temperature you effect the way sound travels through a medium.
The frequency of electromagnetic energy traveling through a medium can change if what changes?
The frequency of electromagnetic energy traveling through a medium can change if the medium's refractive index changes. This can occur when light travels from one medium to another, causing a change in the speed of light, which in turn affects the frequency of the light waves.

What will change the velocity of a periodic wave?
The velocity of a periodic wave is determined by the medium through which it travels and the frequency of the wave. Changes in the medium's properties (such as density or elasticity) can alter the wave velocity. Additionally, changes in the frequency of the wave can affect its velocity according to the wave equation.
What causes the amplitude of a wave to change?
The amplitude of a wave changes due to factors such as the energy of the wave, the medium through which it travels, and any obstacles or interference it encounters.
When light travels from one medium to another which factors changes?
When light travels from one medium to another, factors that change include the speed of light, the wavelength of light, and the direction of light. These changes are caused by the different optical properties of each medium, such as refractive index and density.
How is the wave and its medium connected?
A wave and its medium are connected because the medium is the substance through which the wave travels. The properties of the medium, such as its density and elasticity, affect the speed and behavior of the wave as it moves through it. Changes in the medium can cause the wave to change direction, speed, or amplitude.
Why does light refract when it travels through water?
Light refracts when it travels through water because the speed of light changes as it passes from one medium to another with a different optical density. This change in speed causes the light to bend, or refract, resulting in the change in direction of the light rays.
The frequency of electromagnetic energy traveling through a medium can change if any of the following change except?
The frequency of electromagnetic energy traveling through a medium can change if the medium changes. However, the frequency itself does not change unless the source of the electromagnetic energy changes.
