What else can I help you with?
What happens when a material index of refraction is higher or lower?
When the index of refraction of a material is higher, light slows down and bends more when traveling through that material. This causes the light to be more strongly refracted. When the index of refraction is lower, light speeds up and bends less, resulting in weaker refraction.
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
What happens when a light moves from a material with a lower index of refraction to another material with a higher index of refraction?
The ray of light bends towards the normal.
What happens if light moves from a material in which its speed is lower to one in which its speed is higher the ray is bent away from the?
If light moves from a material with a lower speed to one with a higher speed, it undergoes refraction. This causes the light ray to bend away from the normal line, which is an imaginary line perpendicular to the surface of the material at the point where the light enters or exits. The angle of refraction is dependent on the difference in speed between the two materials.
What happens to the amount of light needed as you move from a lower to a higher magnification?
you are viewing a smaller area so you need less light
Does light travel faster in a material with a higher index of refraction?
No, light travels slower in a material with a higher index of refraction compared to vacuum or air. This is because the speed of light is inversely proportional to the index of refraction of the material according to the equation v = c/n, where v is the speed of light in the material, c is the speed of light in vacuum, and n is the index of refraction.
Would fluorescent material glow if it was illuminated by infrared light?
Not normally - the idea behind florescence is higher energy light (ultra-violet) powers lower energy light (visible light).
A material with a higher or lower R-value is a better insulator?
Higher
Does ultra violet light have a lower or higher wavelength then visible light?
Lower
Is the frequency of blue light higher or lower than violet light?
Blue light has a lower frequency than violet light. Violet light has the highest frequency in the visible spectrum, while blue light has a slightly lower frequency than violet light but higher than green light.
Is the frequency of purple light higher or lower than yellow light?
The frequency of purple light is higher than yellow light. Purple light has a shorter wavelength and higher frequency compared to yellow light which has a longer wavelength and lower frequency.
Does higher energy light have a higher frequency than lower energy light does?
yes
