Letters written on a paper when seen through a thick glass slab appear to be raised. Explain with ray diagram.
Answers
Explanation:
The letters appear raised because of a phenomenon known as refraction. When light travels from one medium to another, it bends (either towards or away from the normal). ... These rays would be refracted on coming out of glass slab (and into air).
Answer:
Letters written on a paper when seen through a thick glad slab appears to be raised. This is because of formation of an raised virtual image.
The writings on the paper act as an object. Now rays originating from the object passes through the glass slab . While passing through the glass-air interface the rays diverge from the normal.
The refracted ray when traced back forms a virtual image , which is raised as compared to the object.
In other words, the normal shift of the image as compared to the object makes it appeared raised.
