What is the radius of curvature of a spherical mirror?Distance from pole to focusDistance from pole to edgeRadius of the sphere of which the mirror is a partHalf the focal lengthQuestion 2 of 203. What is the principal axis of a spherical mirror?Line through pole and focusLine perpendicular to the mirrorLine through pole and centre of curvatureLine along the mirror’s edgeQuestion 3 of 204. Where do parallel rays converge after reflection in a concave mirror?At the poleAt the principal focusAt the centre of curvatureBehind the mirrorQuestion 4 of 205. Where do parallel rays appear to originate after reflection in a convex mirror?At the poleAt the centre of curvatureAt the principal focus behind the mirrorIn front of the mirrorQuestion 5 of 206. What is the focal length of a spherical mirror?Distance between pole and centre of curvatureDistance between pole and principal focusRadius of the mirrorDouble the radius of curvatureQuestion 6 of 207. What happens to an incident ray parallel to the principal axis in a concave mirror?It traces back along the same pathIt passes through the principal focusIt becomes perpendicular to the axisIt passes through the centre of curvatureQuestion 7 of 208. What happens to an incident ray passing through the centre of curvature in a spherical mirror?It becomes parallel to the axisIt passes through the focusIt traces the same path backIt diverges behind the mirrorQuestion 8 of 209. What image is formed when an object is between the focus and centre of curvature in a concave mirror?Virtual, erect, magnifiedReal, inverted, magnifiedReal, erect, diminishedVirtual, inverted, diminishedQuestion 9 of 2010.
