Understand that the energy of electromagnetic radiation is inversely proportional to its wavelength. This means shorter wavelengths correspond to higher energy.
Convert all given wavelengths to the same unit for easy comparison. Typically, nanometers (nm) or meters (m) are used. Remember: 1 cm = 10,000,000 nm, 1 m = 1,000,000,000 nm, and 1 μm = 1,000 nm.
Convert Light B (0.0303 cm) to nanometers: 0.0303 cm * 10,000,000 nm/cm.
Convert Light C (0.000510 m) to nanometers: 0.000510 m * 1,000,000,000 nm/m.
Convert Light D (291 μm) to nanometers: 291 μm * 1,000 nm/μm.
Compare the converted wavelengths. The light with the smallest wavelength in nanometers will have the highest energy.
