What this covers

What is the wavelength of light with a frequency of 6.0 × 10¹⁴ Hz? Use c = 3.00 × 10⁸ m/s. Give your answer in nanometres.
Which list places electromagnetic waves in order of increasing frequency?
The double-slit experiment produces an interference pattern. What does this demonstrate about light?
In the photoelectric effect, increasing the intensity of light above the threshold frequency causes
What is the energy of a photon of frequency 5.0 × 10¹⁴ Hz? Use h = 6.63 × 10⁻³⁴ J·s. Give your answer in units of 10⁻¹⁹ J.
What is the work function of a metal?
Which observations about the photoelectric effect could not be explained by the wave model of light? Select all that apply.
A photocell inside a camera's exposure sensor uses a metal with a work function of 2.30 eV. Violet light of wavelength 400 nm falls on the metal. What is the maximum kinetic energy of the electrons it emits, in electron volts? Use h = 6.63 × 10⁻³⁴ J·s, c = 3.00 × 10⁸ m/s and 1 eV = 1.60 × 10⁻¹⁹ J.
