what is meant by a real, erect ,virtual and diminished image?
Asked by Vishnu Menon | 21st Nov, 2010, 12:00: AM
Please post each query seperately.
An image is said to be real if the rays of light after refraction through a lens actually meet at a point. It is always inverted and can be brought to focus on a screen
An image is said to be virtual if the rays of light after refraction through a lens seem to come from a point . A virtual image is always erect and it cannot be brought to focus on a screen.
An upright image of an object is said to be erect.
If the size of the image formed is smaller than the object, the image is said to be diminished.
We hope this clarifies your doubt.
