1. Commonly, a microscope objective is used to collect the object wave front . 2. Which is also the equation for spherical wave fronts of light. 3. This is like the photons moving as a wave front . 4. Thus the wave fronts will refract, changing direction like light passing through a prism. 5. But it's less of a wave front with each reflection. 6. The new wave front is found by constructing the surface tangent to the secondary wavelets. 7. Einstein asks what makes each electron's wave front " collapse " at its respective location. 8. Both theories describe one-dimensional and steady wave fronts . 9. The distance between successive wave fronts is then increased, so the waves " spread out ". 10. For instance, the tsunami that hit Hawaii in 1946 had a fifteen-minute interval between wave fronts .
