# Focal Length Of A Lens Depends On

Focal Length Of A Lens Depends On. B) both (a) and (b) are false. Focal length depends on the glass inside the lens.the size.space between each element.the curvature of each glass. and when zooming the lens you actually moving these parts closer or farther which result different view `

COMPARE FOCAL LENGTHS Learn when to use different camera from digitaltravelcouple.com

A) the radii of curvature of its surfaces b) the refractive index of its material c) the refractive index of the medium surrounding d) all of these factors. Focal length of a convex lens: (1) take a cylindrical glass tumbler whose height is much greater than the focal length of the lens and fill it with water. such that.

A) focal length of a lens depends on the surrounding medium. Hence. the focal length of a thin convex lens is more than that of a.

#### B) Focal Length Of A Lens Changes With The Object Distance.

The focal length of lens depends on : Focal length of a lens depends on the refractive index of the glass from which it is made. and on the curvature of its two surfaces. Therefore. a thick lens has shorter focal length than a thin lens.

#### Now The Focal Length Of A Lens Depends On The Fact That How Much The Lens Can Converge The Light Rays Passing Through It.

Concept notes videos 411. A) the radii of curvature of its surfaces b) the refractive index of its material c) the refractive index of the medium surrounding d) all of these factors. Focal length depends on the glass inside the lens.the size.space between each element.the curvature of each glass. and when zooming the lens you actually moving these parts closer or farther which result different view `

#### The Power Of Lens Depends On The Focal Length Of The Lens.

A) focal length of a lens depends on the surrounding medium. The focal length of a lens depends on the color of light because of changing the color the wavelength is changed and hence the change into the point of convergence has appeared. They are at equal distance from the optical centre.

#### The Focal Length Of A Lens Determines The Magnification At Which It Images Distant Objects.

(1) take a cylindrical glass tumbler whose height is much greater than the focal length of the lens and fill it with water. such that. The focal length of a lens depends upon the refractive index of the material of the lens and the radii of curvatures of the two surfaces. A) both. (a) and (b) are true.

#### Focal Length Of A Lens Depends On The Refractive Index Of The Glass And Its Curvature.

The focal length of a lens depends on the (i) radii of curvatureof its surfaces and (ii) on the index of refraction of the material the lens is made from. The more highly curved the surfaces. the shorter the focal length. Therefore. the refractive index of the lens material affects the focal length because the refractive index tells us the amount of bending of light when it passes from one medium to another.
