Question

Hоw dоes the роwer оf а соnvex lens vаry, if the inсident red light is reрlасed by viоlet light?​

Answer 1

Answer:

Explanation:

Power of a lens increases if red light is replaced by violet light because P = 1/f = ang - 11/R1 - 1/R2 and refractive index is maximum for violet light in visible region of spectrum

Answer 2

Answer:

Power of a lens increases if red light is replaced by violet light P=1f=(ang−1)(1R1−1R2) and refractive index is maximum for violet light in visible region of spectrum
