Phantasy [73]

Answer:

253.54 nm

Explanation:

h = Planck's constant = 6.626\times 10^{-34}\ m^2kg/s

c = Speed of light = 3\times 10^8\ m/s

\lambda = Wavelength

V = Voltage = 4.9 V

The loss in kinetic energy = Gain in potential energy (energy conservation)

E=eV\\\Rightarrow E=1.6\times 10^{-19}\times 4.9\\\Rightarrow E=7.84\times 10^{-19}\ J

Energy is given by

E=\dfrac{hc}{\lambda}\\\Rightarrow \lambda=\dfrac{hc}{E}\\\Rightarrow \lambda=\dfrac{6.626\times 10^{-34}\times 3\times 10^{8}}{7.84\times 10^{-19}}\\\Rightarrow \lambda=2.53546\times 10^{-7}=253.54\ nm

The wavelength is 253.54 nm
