4 days ago · The focal length of a convex mirror is negative and that of a concave mirror is positive. The object is always placed to the left of the mirror, and the object distance is always positive (for single mirror systems).
4 days ago · We know that focal length is the point on the principle axis of a spherical mirror where the light rays coming from infinity parallel to the axis meet. We also know that focal length is the half the numerical value of the radius of curvature. Complete step by step answer.
6 days ago · See the examples below which will make you comfortable with solving the problems based on the mirror formula. If the distance between the object and the mirror is \(10\text{ cm}\) and its focal length is \(5\text{ cm}\) given it is a convex mirror, find the distance between the mirror and the object.
3 days ago · A convex mirror is needed to produce an image that is three-fourths the size of an object and located $24 \mathrm{cm}$ behind the mirror. What focal length should be specified? 02:44
1 day ago · Focal length is applicable for spherical mirrors because parallel rays are getting focuses at focal point . Whereas in plane mirror, parallel rays reflected and never get to focus. Focal length is not applicable to plane mirror. An object's height is 3cm kept in front of a concave mirror of focal length 20cm.
4 days ago · The focal length of concave mirror will remain constant because its focal length f = \(\frac{R}{2}\), so f does not depend upon µ. The focal length of convex lens will increase, because, in this case focal length is given by \(\frac{1}{f} =(\mu -1)(\frac{1}{R_1} - \frac{1}{R_2}).\) As µ of lens decreases with reference to water.
3 days ago · a) Some students wish to determine the focal length of a convex lens of thickness 0.6cm using an optical pin and a plane mirror. Figure 6 shows the experimental set up when there is no parallax between the pin and the image.
