2. The most powerful laser in the world fires a pulse at 25 fempto seconds producing 30 terawatts of power. In physical sciences, power (watt) = Energy (J or kg•m2•s-2)/time (s). If the average laser fires 7. 5 x 1020 photons in a pulse, then what is the wavelength of the light fired in the world’s most powerful laser?



Answer :

The wavelength of the light fired in the world’s most powerful laser is 37×10⁻¹⁰ nm.

A laser is a device that produces a coherent light beam through optically amplification.

The given data is

Energy = time × power

Energy = 25 ×  30

Energy = 750 J

Photons = 7.5 x 10²⁰

Then the formula is λE =hc

where E = energy,

           h = plank constant,

           c= speed,

           λ = wavelength

wavelength calculation is,

λ = hc / E

λ = 6.62×10⁺³⁴×7.5 x 10²⁰ ×750 J

λ = 37×10⁻¹⁰ nm

The wavelength of the laser is 37×10⁻¹⁰ nm.
