Monochromatic light shines on a surface that has a work function of 1.80 eV. The maximum kinetic energy of the emitted photoelectrons is 0.620 eV. What is the wavelength of the monochromatic light?
Floating-point Expression
A type of expression in programming that allows for the representation of real numbers with fractional parts, using a format that can store a wide range of values.
Double-precision
A format for representing floating-point numbers that uses double the amount of storage compared to single-precision, allowing for increased precision.
Single-precision
Refers to a floating-point number format that uses 32 bits, offering a compromise between range and precision.
