It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power
As a thicker lens has more material to do bend the light further it it would have a shorter focal length
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
The convex lenses are converging lens so when the curvature of the lens increases the focal length will decrease which helps when looking up close. A thin convex lens is for seeing things from a distant.
to determine the focal length of a convex mirror.
A shorter length
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
Which is the shorter length, 175.6 mm or 38.4 cm
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. Lenses whose thickness is not negligible are sometimes called thick lenses.
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
When the object length is less than the focal length
The pitch of each bar is not only determined by the length, but also the thickness and density. The width does not matter. From what I found out, the longer, thinner, and denser the bar, the higher the pitch. The shorter, thicker, and less dense the bar, the lower the pitch.
