Question

An object is placed at 50 cm from a convex spherical mirror with a radius of curvature of 200 cm. What are the properties of the image? O Virtual, m = 0.5 O Real, m = 0.67 Virtual, m = 0.67 Real, m = -1.0 Real, m = 1.0

Answer 1

Solemon object distance, u = -50cm Radius of curvature, R= 200 cm → focal focal length f= & 200 = 100cm all Hoco, using minor f formule -154 = + > - ㅗ -so tol u 100 <l <1- 1 i + = 1+2-3 100 니 50 100 100 100 cm V= - = v= 3 33.33 cm since image distance is positive This image is formed behind the mirror. So, the im Now, magnification is given by 100 3 -50 > m=0.67 Ano;- virtual, m=0.67 image is virtual m= 100 u 150
