A parallel beam of light is incident on the system of two convex lense – InterviewSolution

1.	A parallel beam of light is incident on the system of two convex lenses of focal lengths f1=20 cm and f2=10 cm. What should be the distance between the two lenses so that rays after refraction from both the lenses pass undeviated ?
