Question 1

A laser used in some laser pointers has a wavelength of 405 nm. What is the frequency of this light in hertz (s^-1)?

◦ 7.41 × 10⁵ s^-1
◦ 1.35 × 10^-13 s^-1
◦ 1.35 × 10^-6 s^-1
◦ 7.41 × 10¹⁴ s^-1
◦ 1.22 × 10² s^-1

Question 2

A line in the spectrum of atomic mercury has a wavelength of 258 nm. When mercury emits a photon of light at this wavelength, the frequency of this light is:

◦ 8.61 × 10^–16 s^–1

​

◦ 7.70 × 10^–19 s^–1

​

◦ 1.16 × 10¹⁵ s^–1

​

◦ 77.3 s^–1

​

◦ none of these are correct
