Question

What did Huygens explain by assuming zero amplitude of secondary wavelets in the backward direction?

पर्याय

• The radius of a secondary wavelet

• The double refraction shown by calcite

• The geometry of Saturn’s rings

• The absence of the backwave

Answer 1

Huygens used the adhoc assumption of zero backward amplitude to explain the absence of the backwave. The assumption addresses a shortcoming of his construction.
