Question 5 - Assertion Reasoning Questions (MCQ) - Chapter 10 Class 10 - Light - Reflection and Refraction

Assertion (A): If the rays are diverging after emerging from a lens; the lens must be concave.  

Reason (R): The convex lens can give diverging rays.  

Answer 

• It is not necessary that if the rays are diverging after emerging from the lens then the lens is concave.
• In Convex lens , if object is between O ptical Center and F ocus, the rays are diverging
  
• If the rays crossing the focal point of the convex lens, become diverging.  
• Therefore, lenses can be concave or convex. 

Thus,

• Assertion is false
• Reasoning is true

So, the correct answer is (d)
