Explanation Given info: The distance of the person from the concave mirror is 30.0 cm and the magnification is 1.50 times. The expression for magnification of the image is, m = − b a Here, a is the distance of the person from the mirror b is the distance of the image from the mirror. Rearrange the above equation for the value of b . b = − m a Substitute 30.0 cm for a and 1.50 for m in the above expression. b = − ( 1.50 ) ( 30.0 cm ) = − 45 cm The expression for the focal length of concave mirror is, 1 f = 1 a + 1 b Here, a is the distance of the object. b is the distance of the image. Rearrange the above equation for the value of f . f = a b a + b Substitute − 45

Ray Optics

Optics is the study of light in the field of physics. It refers to the study and properties of light. Optical phenomena can be classified into three categories: ray optics, wave optics, and quantum optics. Geometrical optics, also known as ray optics, is…

Converging Lens

Converging lens, also known as a convex lens, is thinner at the upper and lower edges and thicker at the center. The edges are curved outwards. This lens can converge a beam of parallel rays of light that is coming from outside and focus it on a point on…

Lateral Magnification

In very simple terms, the same object can be viewed in enlarged versions of itself, which we call magnification. To rephrase, magnification is the ability to enlarge the image of an object without physically altering its dimensions and structure. This pr…
