Why wouldn t you want to use a specular reflector as a movie screen?
Why wouldn’t you use a specular reflector as a movie screen? It would reflect all the light, blinding those who could see it and not allowing others to see it at all. The air doesn’t scatter light like the wall does, but if the beam were strong enough or if the air were thick enough, you could see it.
What color corresponds to the maximum sensitivity of the eye Fig 6.2 in bright light in dim light?
6.2). in bright light? In dim light? The maximum sensitivity is in the blue-green range which is 507 nm.
When selecting cheek and lip makeup they should be from a different color family than the eye makeup?
When selecting cheek and lip makeup, they should be from a different color family than the eye makeup. Hair color should always be taken into account when determining makeup colors.
Why are clouds white quizlet?
Clouds are white because their ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light. They are Cirrus clouds.
What color travels the slowest in glass?
Violet
Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.
What happens if you project onto a mirror?
Using a mirror would make the image appear different for different audience. The left part of the diverging beam falling onto the mirror would mostly reflect to the left side and can only be seen by the audience on the left side and vice-versa. This wouldn’t be a case with a screen which diffuses light falling onto it.
How does light travel through retina?
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
What are the steps of visual processing in the correct order?
For children with normal vision, the following things happen in this order:
- Light enters the eye through the cornea.
- From the cornea, the light passes through the pupil.
- From there, it then hits the lens.
- Next, light passes through the vitreous humor.
- Finally, the light reaches the retina.

What do we see when we see a cloud quizlet?
What do we see when we see a cloud? We see water droplets. A snow crystals stops growing soon after it falls from the cloud.
Can a diffuse reflector be used for shaving?
You would not want to use a diffuse reflector when shaving or applying makeup because when light falls on a rough surface the light is reflected in every direction and you cannot see your own reflection. Can the image formed by a concave mirror be either larger or smaller than the object?
How does polishing cause diffuse reflection of light?
Polishing produces some specular reflection, but the remaining light continues to be diffusely reflected. The most general mechanism by which a surface gives diffuse reflection does not involve exactly the surface: most of the light is contributed by scattering centres beneath the surface. Figure 3.1c shows diffuse reflection from a rough surface.
Why are reflectors and diffusers important in photography?
Reflectors and diffusers manipulate the light in your image, and as such, can change the overall look considerably. They are essential tools for the close-up photographer.
Do you need flat surface for diffuse reflection?
A flat surface is indeed required to give specular reflection, but it does not prevent diffuse reflection. A piece of highly polished white marble remains white; no amount of polishing will turn it into a mirror. Polishing produces some specular reflection, but the remaining light continues to be diffusely reflected.
