The wavelength of a photon that has an energy of 7.53* 10^-32
Molodets [167]

Answer:

= 2.64 × 10^7 m

Explanation:

Energy is given by the formula;

E = hc/λ

Where h is Planck’s constant (= 6.626 x 10^-34 Js), c is the speed of light (3.00 x 108 m/s) and λ is the wavelength in meters.

Therefore, wavelength will be given by;

λ = hc/E

  = (6.626× 10^-34 × 3 × 10^8)/(7.53 × 10^-32)

<u>   = 2.64 × 10^7 m</u>

If you want to measure a volume of 8 microliters that could be done with two different micropippetors (the 1-10 uL or 2-20 uL).

You should choose 1-10 uL pipette !  

Small range  measurement scales are more efficient than large range scale because they give more accurate measurement as they have visible marks on it  small for all measurement.
