For Questions 6 to 9, two statements are given –one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the options given below.
A. Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. Assertion and Reason are true but Reason is NOT the correct explanation of Assertion.
C. Assertion is true but Reason is false.
D. Both Assertion and Reason are false.

Q6. Assertion (A): The work function of a given material increases with an increase in the frequency of the incident radiation
Reason (R): As per Einstein’s photoelectric equation hν = φ + KE, work function φ is directly proportional to the frequency ν of the incident radiation

Q7. Assertion (A): The conductivity of intrinsic semiconductors increases with an increase in temperature.
Reason (R): Increase in temperature decreases the average time between collisions of electrons.

Q8. Assertion (A): If the focal length of two convex lenses is the same, the lens with the larger diameter will produce brighter images.
Reason (R): Convex lenses with larger diameters are able to focus light better.
