Does the frequency or wavelength of a laser affect the velocity of the light wave projected by the laser?
No. The frequency of the entire electromagnetic spectrum varies continuously from low to high frequency. The speed of light remains a constant 186,000 miles per second. That is 300,000 km/sec.
What happens to the speed and wavelenght and frequency of a wave when it reaches the boundary between two media?
Frequency never changes since it depends only on source. Speed can either increase or decrease, depending on the direction of travel of light. This would cause an increase or decrease in wavelength respectively. Speed increases when light travels from an optically denser medium to an optically less dense one. (For example, when light travels from water to air) Speed decreases when light travels from an optically less dense medium to an optically denser medium.
When light wave change its medium from dense to rare frequency increases or decreases?
Frequency doesn't change in the transition between media. Speed changes, with a consequent changein wavelength. In passing to a less-dense medium, speed and wavelength both increase.
Does light travel faster in diamond or water?
Light travels slower through denser media, so it travels faster through water than through a diamond.
Does light bend as it passes through materials?
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
Why wavelenth changes with speed of light?
Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.
Which characteristic of a wave changes as the wave travels across a boundary between two different media?
The essential characteristic that changes is the speed of the wave. The wavelength also changes. Amplitude and polarization can change. What does not change is the frequency.
How is the frequency of light affected when going between different media?
Once the light leaves the source, its frequency doesn't change, no matter what ittravels through or what kind of exciting adventure it encounters.But if it passes from one medium to another one with a different index ofrefraction, then the speed and wavelength change, and the direction of aray of light may change.

When is the speed of light increases or decreases after refraction?
Refraction comes into play only when the light travels from one medium into another medium. The speed of light is different in different media, so the wavelength changes due to refraction. The formula for wavelength is the ratio of the speed of light to its frequency. The most important point is that the frequency character of light remains constant eventhough it travels in different media. Hence the wavelength is directly proportional to the speed of light. So as speed changes, the wavelength also changes accordingly.

Does light travel faster in diamond or water?
Light travels slower through denser media, so it travels faster through water than through a diamond.
Why does light refract?
Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.
Does the speed of light differ?
The speed of light is different in different media; light travels more slowly in water than it does in air, for example.
Does light bend as it passes through materials?
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
How fast does light travels in miles?
186,282 miles per second, in vacuum. Slower in material media.
