Calculate the time duration of a laser pulse

Reference no: EM131000670

Laser pulses of femtosecond (10^-15 s) can be produced but is makes no sense of talking about color of such pulses. To appreciate this, calculate the time duration of a laser pulse whose range of frequency covers visible spectrum, 4.0x10^14 to 7.5x10^14 Hz.
