What causes light rays passing through it to diverge?
double concave lens
What causes light rays passing through it to refract?
double concave lens
What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.
How does light travel through a convex lense?
light rays converge at the focal plane
Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.

What happen when light passes through a regular lens?
1. - It is refracted (bent) relative to the source. 2. - The spectrum is separated, the amount depending on the thickness and curvature. 3. - A small part of the light is reflected off the lens, not passing through it. 4. - Assuming a 'perfect' regular (convex) lens, all light passing through the lens focuses at a single point in space, (focal point). 5. - Any image passing through the lens is reversed, equidistant from the focal point.

How does light travel through a carvex lens?
IF you meant a convex lens - light entering the lens is bent because it's passing from one medium to another - to converge at the focal point.
How does light travel through a convex lense?
light rays converge at the focal plane
What happens to light that passes through a convex lens?
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.

Why does astigmatism affect your night vision?
At night, the pupil dilates to let in more light. Astigmatism is a distortion in the cornea that causes different focal lengths for light passing through different parts of the cornea into the lens. With a small aperture (constricted pupil), the differences do not cause noticeable blurring; just as in a camera, a small aperture gives greater depth of field. At night, when the aperture is larger (dilated pupil), the eye has less depth of field, so the imprecise focal length of the eye causes the image to be noticeably blurred.
What causes water to bend light passing through it?
because when light hits a different martial it slows and change it direction like ridingbike from the road on to the sand.
What effect has the condenser lens on light rays passing through it?
The condenser adjusts the amount of light passing through the specimen.
Can you split white light by passing through it through a prison?
You can split white light into a spectrum of its component wavelengths by passing it through a prism, not a prison.
