A convex lens made of glass is immersed in water.as a result.its focal length will increase. These types of lenses can converge a beam of light coming from outside and focus it to a point on the other side.

#### 10 Cm Is The Focal Length Of The Convex Lens.

It is the point where parallel rays of light meet or converge. To verify experimentally that the focal length of a lens depends on its surrounding medium. The lens maker’s equation for the focal length. f. of a lens is1 1 f =(n− 1) 1 r1 + 1 r2.

#### Find The Position And Nature Of The Image Formed By This Combination.

The focal length varies with the sign (positive or negative) depending upon the nature of the lens and mirror (concave or convex). The distance between the convex lens or a concave mirror and the focal point of a lens or mirror is called the focal length. Focal length of lenses 2 the focal length of a thin lens depends on the radius of curvature. r.of each surface of the lens. and the index of refraction. n. of the lens material.

#### The Convex Lens Has The Property Of Converging The Light Rays Passing Through It.

To get a well illuminated and distinct image of the distinct object. the distant object should be well illuminated. There should not be any hurdle between the rays of light from the object and the convex lens. According to the question. focal length is f = +25 cm image is virtual and magnified. with magnification (m) = +2 for a lens. expression for the magnification is m = v / u or. +2 = v / u therefore. we can write = v = 2u expression for the lens formula is. […]

#### As A Result. The Effective Focal Length Of The Combination Becomes 2 F.

The focal length of a plano convex lens is ′ f ′ and its refractive index is 1.5. This point is known as the focus and the distance between the center of the lens to the focus is called the focal length of convex lens. The focal length of a lens is a point where the parallel lines passing through the lens meet after converging.

#### Both Convex Lens And Concave Mirror B:

The placing of the convex lens should be vertical. The power of a lens depends upon the curvature and focal length (f). The eyepiece of a microscope is a concave lens.
