What are the crest and trough of a wave?
A wave has a frequency of 10 Hz and a wavelength of 3 meters. If the frequency is increased to 15 Hz, what is the new wavelength?
An electron transition in a hydrogen atom emits a photon with a wavelength of 486 nm. Calculate the energy of the photon in electronvolts (eV), given 1 eV = 1.602 x 10^-19 J.
Which of the following statements best describes the impact of increasing frequency on light energy and wavelength?
