Difference between corpuscular and wave theory
| Corpuscular theory | Wave theory |
| According to this theory light consists of small particles called corpuscular. Light particles travel with the velocity of light in the straight line. Light travels with faster velocity in the denser medium. | According to wave theory light is a form of energy because it travels in the form of a wave. Waves travel with the velocity of light but not in the straight line. Light travels with slow velocity in the denser medium. |
