Question : An image which cannot be obtained on a screen is called a ____________.
Option 1: virtual image
Option 2: real image
Option 3: vector image
Option 4: spectral image
Correct Answer: virtual image
Solution : The correct answer is a virtual image .
Virtual images cannot be projected onto a screen because they do not involve the actual convergence of light. A virtual image is formed when extended or diverging light rays appear to converge but do not meet. These rays only appear to converge when extended backwards. These images are typically formed when the object is located inside the focal point of a converging lens or mirror.
