In a galvanic cell, electrons flow from the anothe to the cathode.
I hope you got the answer
The units for mass are grams (g) and kilograms (kg)
the units for volume are millilitres (ml) and litres (l)
Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ
(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ
4.007*10⁻⁷ m = λ
The wavelength of the yellow light = 4.007*10⁻⁷ m
