the electric field associated with a light wave is given as
E=E₀sin[(1.57x10⁷ m^-1)(ct-x)]

Find the stopping potential when this light is used in an experiment on photoelectric effect with emitter having work function 2.1eV.

Being beaten is often a temporary condition, giving up is what makes it permanent.
