Answer:
The longest wavelength of light that is capable of ejecting electrons from that metal is 1292 nm.
Explanation:
Given that,
Wavelength = 400 nm
Energy
We need to calculate the longest wavelength of light that is capable of ejecting electrons from that metal
Using formula of energy
Put the value into the formula
Hence, The longest wavelength of light that is capable of ejecting electrons from that metal is 1292 nm.
