WebFizeau's measurement of the speed of light in air. In 1848−49, Hippolyte Fizeau used a toothed wheel apparatus to perform an absolute measurement of the speed of light in air. Subsequent experiments performed by Marie Alfred Cornu in 1872–76 improved the methodology and made a more accurate measurement. WebAccording to Einstein's theory, the energy of a photon is. Question options: 1) proportional to its wavelength. 2) proportional to its frequency. 3) constant, since the speed of light is a constant. 4) quantized, since it always appears in bundles of size, 1.6 ´ 10-19 C. 5) proportional to the square of the frequency.
