When light traveling through one material reaches a second material, some of the light will be reflected, and some of the light will enter the second material. At the point at which the light enters the second material, the light will bend and travel in a different direction than the incident light.

Regardless of whether light is acting as particles or waves, however, the result of reflection is the same. The reflected light produces a mirror image. The amount of light reflected by an object, and how it is reflected, is highly dependent upon the degree of smoothness or texture of the surface.

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes direction.

Wave speed, frequency and wavelength in refraction Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes.

(1) Light waves can travel through a vacuum, but sound waves cannot. (2) Sound waves have greater amplitude than light waves. 27 What happens to the speed and frequency of a light ray when it passes from air into water? (1) The speed decreases and the frequency increases.

3 Answers. Frequency depends only on the source of the wave. The wave may encounter a denser medium in its travels, in which case it will slow down and its wavelength will get shorter.

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. The equation that relates wavelength and frequency for electromagnetic waves is: λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.

The frequency of the system is a constant because it is essentially the square root of stiffness divided by mass with some variation due to boundary conditions. As long as these remain constant, so will the frequency.

In shallower water near the coast, waves slow down because of the force exerted on them by the seabed. Even if waves are coming in from deep water at an angle to the beach, the move to shallower water means that the waves will slow down and curve around (refract) so they are more parallel as the surf hits the beach.

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.

A shallow water wave’s speed is dependent on ocean depth. If part of a wave is in shallower water then it will travel slower. A shallow water wave’s speed is dependent on ocean depth. If part of a wave is in shallower water then it will travel slower.

Light waves will speed up or slow down when they enter or exit a material of a different optical density, which is the refractive index of the material. The deeper the water, the faster the waves travel, and so waves will refract (change direction) when they enter deeper or shallower water at an angle.

As a wave enters deeper water the height and potential energy decrease. Therefore the speed of the wave must increase. Potential energy converted to kinetic energy.

If there is any flow, the stream will have its own vertical shear (left diagram in Fig. 5.1). In general, the faster the flow, or the shallower the water, the greater the shear so the greater the difference in resistance.

This MODIS image of blue water in the Caribbean Sea looks blue because the sunlight is scattered by the water molecules. Near the Bahama Islands, the lighter aqua colors are shallow water where the sunlight is reflecting off of the sand and reefs near the surface.

A wave with a longer wavelength travels at higher speed. In contrast, shallow-water waves show no dispersion. Their speed is independent of their wavelength. The deep ocean is shallow with respect to a wave with a wavelength longer than twice the ocean’s depth.

4.18 A). When deep-water waves move into shallow water, they change into breaking waves. When the energy of the waves touches the ocean floor, the water particles drag along the bottom and flatten their orbit (Fig. When this happens, the front surface of the wave gradually becomes steeper than the back surface.

Surging breakers occur when long wave period, low amplitude waves approach moderately steep shores. The wave doesn’t spill or curl; it builds up and then slides rapidly up the beach with less foam or spray than the other two breakers.

The right term for a wave hitting a beach and then retreating is called “a receding wave”. The motion of the waves are caused by tides and the orbit of our moon, which causes the waves to go back and forth.

The frequency of a ware is the number of complete waves that pass a given point in a certain amount of time. Frequency can also be described as the number of vibrations ser second. Frequency is measured in units called hertz (Hz). ae oration that occurs every second has a frequency of 1 Hz.

The distance between two consecutive compressions or rarefactions in a wave is called the wavelength.
