When ultraviolet light with a wavelength of 400 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is 1.10 eV.
What is the maximum kinetic energy Ko of the photoelectrons when light of wavelength 350 nm falls on the same surface?
Use h= 6.63×10-34 J * s for Planck's constant and c= 3.00×10^8 m/s for the speed of light and express your answer in electron volts.
I think it is C , idk why, but I just learn about this and I think it is.... sorry I didn't really help.....
Dx = 20m
V1 = 10m/s
g = 9.8m/s^2
(delta-t) = 2sec
dy = 19.6m
Answer: wavelength=velocity×period
Explanation:the relation between velocity, wavelength and period is
Wavelength=velocity×period
