Rod cells in the retina of the eye detect light using a photopigment called rhodopsin. 1.8 eV is the lowest photon energy that can trigger a response in rhodopsin. What is the maximum wavelength of electromagnetic radiation that can cause a transition? In what part of the spectrum is this?
The most energetic electromagnetic waves in the universe are gamma-rays from gamma ray bursts (GRBs) from collapsing massive stars, observed by satellites with expected energies of 100 TeV (1 TeV = 1012eV).
1. What is the frequency of these energetic gamma ray photons? 1 eV = 1.60 x 10-19 J.
2. What is the wavelength?
A microwave oven produces electromagnetic radiation in the radio portion of the spectrum. These microwave photons are absorbed by water molecules, resulting in an increase in the molecules’ rotational energies. This added energy is transferred by heat to the surrounding food, which as a result becomes hot very quickly. If the energy absorbed by a water molecule is 1.0 × 10-5 eV, what is the corresponding wavelength of the microwave photons?
a. 1.22 GHz
b. 2.45 GHz
c. 4.90 GHz
d. 9.80 Hz
