The sun subtends an angle (1^(@))/(2) at the pole of a concave mirror. If the radius of curvature of the mirror is 15 m , what will be the size of the sun's image formed by the mirror?

The diameter of the sun subtends an angle of 0.5^(@) at the pole of the concave mirror. The radius of curvature of the mirror is 1.5 m. Find the diameter of the image of the sun. Consider the distance of sun from the mirror infinite

The sum subtends an angle 0.5^(@) at the center of a concave mirror having radius of curvature 1 m. What will be the diameter of the image of the sun formed by the mirror?

The sun subtends an angle half a degree at the pole of a concave mirror which has a radius of curvature of 15 m. Then the size (diameter) of the image of sun formed by the convace mirror is

The sun subtends an angle half a degree at the pole of a concave mirror which has a radius of curvature of 15 m. Then the size (diameter) of the image of sun formed by the concave mirror is

The sun (diameter = D) subtends an angle of theta radians at the pole of a concave mirror of focal length f . The diameter of the image of the sun formed by the mirror is

Rays from the sun subtend an angle theta (in radian) at the pole of a concave mirror of focal length f. If the diameter of the sun is D the diameter of the image of the sun formed by the mirror is-
