Question

Every great physical theory starts as a heresy and ends as a dogma

Answer 1

Hello!!

_________________________________

$\Huge{\mathfrak{\pink{\underline{ANSWER}}}}$

❇️ A common observation in our daily life is that light travels in straight line.

❇️ When Huygens propounded his wave theory, it was a heresy.

❇️ However, soon it became a dogma as interference patterns, refraction etc., could be successfully explained on the basis of wave theory.

❇️ It was believed that light was only energy but when photoelectric effect was discovered it was proposed that light had a particle nature too, this was greatly debated and treated as a hearsay.

❇️ However Einstein finally proved it with his quantum theory of light.

❇️ Henceforth, it has been treated as a dogma.
