• A. The angle between the refracted ray extended forward & the emergent ray extended backward is called angle of deviation.
• B. The angle between the refracted ray extended backward & the emergent ray extended backward is called angle of deviation.
• C. The angle between the incident ray extended forward & the refracted ray extended forward is called angle of deviation.
• D. The angle between the incident ray extended forward & the refracted ray extended backward is called angle of deviation.
• E. The angle between the incident ray extended forward & the emergent ray extended backward is called angle of deviation.

Answer 1

The correct option is E

The angle between the incident ray extended forward & the emergent ray extended backward is called angle of deviation.
