What is phase change in light of wavelength 600-NM incident in a material with index of refraction n equals 1.38 when it reflects from a material with index of refraction n equals 1.40?

A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
.05 mm
What is chlorophyll responsible for?
It is the part of a molecule that is responsible for its color. When a molecule absorbs a wavelength of visible light and reflects or transmits others, this is when the molecule's color will appear.
What is a colored material that abosrbs some colors but reflects others?
Sounds like everything you can see.
Whats the difference between reflection and refraction?
Reflection is when a wave comes into contact with something and then returns to the medium from which it came. Refraction is when direction of a wave changes due to a change in it's phase velocity. For example, when light goes through a window, it refracts, but you can slightly see yourself in it, because a fraction of the light also reflects. Another example, I'll use an arrow. If the arrow goes this way ------> and then hits a wall and comes back this way and bounces off and goes this way, ^ it has Refracted.^^^^
Is everything reflective?
yes. the colour depends on how much light a material reflects. shadows aren't as a shadow is an abscence of light
What is a ideal mirror?
An ideal mirror is one which reflects all incident radiation, without any distortion, absorption or refraction.

What are two things that determine the color of a light wave?
the two things that determine the color of a light wave are its wavelength and the material it reflects from.
What is the name for the way in which a mineral reflects light?
Refraction
What is used to describe how the medium reflects light?
Index of refraction
What is used to describe how medium reflects light?
Index of refraction
Which object or material reflects infrared rays?
All materials will reflect, absorb and transmit (allow to pass through) electromagnetic radiation. This is called the Transmit/Reflect (T/R) ratio and it will vary for a material based on the wavelength of the incident radiation. IR radiation does not transmit through most materials. It is absorbed/reflected. Metalized Mylar has a small transmit/reflect ratio.
What color light is refracted the most?
violet or the blue side of rays refract moreRefraction is the change in direction of a light beam commonly caused as it passes from one medium to another. Snell's law relates the angle of incidence and angle of refraction by n1 * sin(theta1) = n2 * sin(theta2).The reason different wavelengths of light refract at different angles in a medium (such as water or glass) is because the index of refraction (n2) varies by wavelength, this variation with wavelength is known as dispersion.In most materials that you would observe refraction, the index of refraction decreases with wavelength. This is called normal dispersion. (If the index of refraction increases with wavelength, it's called anamolous dispersion.)Thus, in glass (prisms) or water (rainbows), which exhibit normal dispersion, the index of refraction is greater for shorter wavelengths. Violet light, which is the shortest wavelength of visible light, will refract the most.by the way- this is not my thought, I got this from yahoo! UK and Ireland' from a guy named askbrian
Why in Light refraction do black objects remain black?
Light "refraction" is the bending of light as it passes through a transmitting medium, Refraction has nothing to do with black objects. A black object reflects no parts of the visible part of the spectrum, it absorbs them all. A white object reflects all parts of the visible spectrum. A red object reflects the red part of the spectrum, absorbing the rest.
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
Why is it necessary for the angle of refraction to be equal to the angle of incidence when the angle of incidence is zero?
when the angle of refraction is zero you still need an angle of incidence because it still reflects back.
The fraction of incident light that a body reflects is known as its?
" albedo "
