Legends are watching before the exam😂
Dude it true
Current I am one of the legends
Actually 😂😂
Everyone is watching before the exams only
How can the person watch after the exam😎😎😎
😂😂🖐
Your animation and explanation is the best 😊😊😊
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 ..
madam one 0 is extra that can be ignored
Yes you're right
I agree it is a mistake in typing
@@ManpreetKaur-nf7hp adding of one 0 changed the complete value.. It becomes 2 lakh...now see the comparison between 2 lakh and 20 thousand...
@@sweetsisterskkrm8773 u r wrong

Your explanation is helpful for me
Good explanation 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
S plz change it

Hi Sir, the explanation was good!! ✌ But, there wasn't any information given about the types of music instruments as in the NCERT Book...

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.
Grade 8 friction?
Good work 👏
why we hear loud soud in night some pair to day
as there are less vibrations produced during night as compared to the daytime.
