Question

(A.F
3. The value of Planck's constant is 6.63 x 10-34 Js.
The velocity of light is 3.0 x 108ms-1. Which value
is closest to the wave length in nanometers of a
quantum of light with frequency 8x 1015 -19
(A) 4 x 101
(B) 3 x 107
(C) 2 x 10-25
(D) 5 x 10-18 please solve this and explaim it​

Answer 1

Answer: A

Frequency (v)=cλ=3×108ms−18×1015s−1

=0.375×10−7 m

=3.75×101nm≈4×101 nm
