Physics of waves: Covers Quantum Waves, sound waves, and light waves. Easy to understand explanation of refraction, reflection, and many other topics.
Important correction: In the section of refraction, the colors are reversed. Violet light slows down in water more than red light, and violet light therefore bends more than red light when it transitions from air to water.

Arithmetic Progression (AP) and Geometric Progression (GP) - Both super important concepts explained in this video. ⁣To summarise, An arithmetic Progression is a sequence with the difference between two consecutive terms constant. And a geometric Progression is a sequence with the ratio between two consecutive terms constant.


⁣In this video, we will learn:
0:00 Arithmetic Sequence
0:41 nth Term of Arithmetic Sequence
1:20 Average of n Terms in Arithmetic Sequence
1:34 Sum of Terms in Arithmetic Sequence
2:38 Geometric Sequence or Progression
4:11 nth Term of Geometric Sequence
