Sir, 09:33, For human ears, the range of audible frequencies is roughly from 20 Hz to 20,000 Hz sir. The sounds above 20,000 Hz are called ultra sonics. But you have written it as 20 Hz to 2,00,000 Hz. Only dogs and whales can hear those sounds sir. You can edit that point alone sir ..
I want to say this mistake at 9:36, A human ear can hear sound from 20 to 20,000 hz only but sir you have kept 20 to 200000 hz, this is a big mistake which even costs 1 mark or 2 marks or maximum 5 marks, plz update it
This is more better than my science teacher explain i really hate my teacher she will always ask me question. Am not telling that she should not ask but wantedly when I was absent on that day whatever she explained i need to say what is this 😔
Your explanation is very good but you made a mistake in this video in the summery that is the audible sound is 20Hz to 20,0000,Hz ,,,,but the answer is 20Hz to 20,000Hz
Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound.

madam one 0 is extra that can be ignored
Yes you're right
I agree it is a mistake in typing

What is sound definition
Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound.
why we hear loud soud in night some pair to day
as there are less vibrations produced during night as compared to the daytime.
