Solution

Speed of light, c = m/s
Frequency range =
Speed of light = frequency x wavelength

For frequency =
$capital lambda =Â fraction numerator 3 cross times 10 to the power of 8 space m divided by s over denominator 3.75 cross times 10 to the power of 14 space H z end fraction equals 8 cross times 10 to the power of negative 7 end exponent m space equals 8000 â�«$

For frequency =
$capital lambda =Â fraction numerator 3 cross times 10 to the power of 8 space m divided by s over denominator 7.5 cross times 10 to the power of 14 space H z end fraction equals 4 cross times 10 to the power of negative 7 end exponent m space equals 4000 â�«$

Wavelength range = 4000Å to 8000Å
