The nature of image formed by a convex mirror for any object position is :
Virtual, erect and diminished
A convex mirror is a diverging mirror, and for any position of the object in front of it, the reflected rays appear to diverge from a point behind the mirror.
This always produces a virtual image that is erect (upright) with respect to the object and diminished (smaller) in size compared to the object, regardless of how far or near the object is placed.
Real images, inverted images, or enlarged images are not possible with a convex mirror for any object position, unlike a concave mirror where the image nature varies.
Therefore, the image formed by a convex mirror for any object position is virtual, erect and diminished.
A student is performing an optics experiment using a glass slab. A laser beam is found to travel through the glass at a speed of \(2 \times 10^8\, m/s\). If the speed of light in air is \(3 \times 10^8\, m/s\), what is the refractive index of the glass slab ?
Two convex lenses have focal lengths of 50 cm and 25 cm, respectively. If these two lenses are placed in contact, then the net power of this combination will be equal to
The refractive index of crown glass is close to 3/2. If the speed of light in air is c, then the speed of light in the crown glass will be close to
Tyndall effect is a phenomenon of
