Thank you, this is all a pretty new experience and I have been out of physics for years, jumping right into modern .. I realized my math error that shortly after I posted, Too many hours doing work in front of the computer, Sorry haha, But is this really a reasonable answer for Δλ... Δƒ=1/4πΔt...

Δf ≠ 1/4πΔt it is supposed to be Δf = h/4πΔt I thought??

Homework Statement 1) Very short laser pulses can be produced, on the order of a few femtoseconds. (look it up.) If a laser has a center wavelength of 800nm, and lasts for 20 femtoseconds, (2*10-14s) what spread of wavelengths must it have to be compatible with the time-energy uncertainty...

Hey, my name is Joey and I'm a physics minor and need some help with modern physics, so here I am!
