If the visible wavelengths of light range from 400 nm to 750 nm, what is the highest frequency associated with visible light?
a. 2.3 × 1020 Hz
b. 3.0 × 108 Hz
c. 7.5 × 1014 Hz
d. 5.0 × 108 Hz
highest frequency corresponds to least wavele3
f = c/L = 3* 10^8 / (400* 10^-9)
f = 7.5* 10^14 Hz
========
Comment before rate in case any doubt, will reply for sure.. goodluck
