The angle of refraction increases, though it's a function of curvature rather than actual thickness.

How does change in the thickness of lens change the focal length of lens?

Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.


How thickness effects on focal length of convex?

As the thickness of a convex lens increases, the focal length decreases. This is because a thicker lens has a more curved surface, which causes light to converge more quickly. The focal length is the distance at which the light converges, so a thicker lens leads to a shorter focal length.


How does thickness of convex lens affect focal length?

The focal length of a lens depends on 1. The refractive index of the material 2. Radii of the curvature of the two faces. The lens maker's formula is 1/f = (mu --1) (1/R1 --1/R2) mu- the refractive index of the material with which lens is made R1 and R2 are the radii of curvature of the faces. f- the focal length of the lens thus formed. your question needs clear information. As the thickness of the lens of same diameter is increased then radii of curvature would decrease, hence focal length would decrease. But as the diameter gets increased then there comes a chance of maintaining the radii of curvature to be the same. If so, then no change in the focal length. But, if diameter is not increased to the right extent then we cannot be sure about the variation of focal length.


What happens if you decrease a telescopes eyepiece focal length?

The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)


Will focal length of a concave mirror would increase decrease stay the same if the mirror were made flatter?

If a concave mirror is made flatter, its focal length will increase. This is because a flatter mirror has a larger radius of curvature, resulting in light rays converging at a point farther away from the mirror.


For a research telescope (with a long focal length) would the thickness be greater or less than for a backyard telescope (with a short focal length)?

Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.


Eye has fixed focal lengthThen how can you say that the focal length of changes?

The eye has variable focal length, its lense varies with thickness in order to focus to distant or nearby objects. Focal distance is constant, from lense to retina.


How does the thickness of a lens affect the focal length of a lens?

There are three factors affecting the focal length of a lens. 1. refractive index of the material of lens. 2. refractive index of the surrounding medium 3. the radius of curvature of the lens surfaces.


What would be the effect on magnification to increase the focal length of microscope and telescope?

The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.


Does the field of view narrow when focal length increase?

yes


How is magnifying power of telescope and a microscope are a affected by increasing the focal length of their objectives?

The magnification of a telescope M is the the focal length of the objective Fo over the focal length of the eyepiece Fe so increasing the focal length of the objective increases the magnification. The magnification of a microscope M is approximately tube length L/Fo x 25/Fe. Therefore increasing the focal length of the objective reduces the magnification.
