Sir, your videos really help me alot. Thanks alot sir😇 actually i had a doubt at 48:35, Isn't the wavelength is the distance from one crest to anothervor from one trough to another , then the ans will be 3rd option CE ( half the wavelength).
There is one mistake done here... compression is when the objects are close and .. rarefaction is when the objects are distant from one another but in the video it is given the opposite..
1:37:26 Anvil Stirrup Hammer. BTW thankuh very much for teaching this also because though it's deducted from syllabus but still coming in my exam. So, thankuhh veryy muchh ❤
Thanks sir you are the best teacher you really make me understand what the sound chapter is ? Thankyou for your efforts Now i will definitely pass my annual examination of science THANKYOU SIR ❤ 1:06:27
48:45 sir wavelength means the length between two consecutive compression or rarefaction but there is only one compression and one rarefaction. The answer for that question is AE

HW
t = 3.42s
v = 1531 m/s
d = ?
v = 2d/t
1531 = 2d/3.42s
2d = 1531 × 3.42s
2d = 5236.02
d = 5236.02/2
d = 2618.01 m
Hence, the distance of seabed from the ship is 2618.01 m
Mine is 2616.3m
Mine 2618.01 too

Sound waves is called machanical wave because it requires a material medium to travel or propagate

1:40 the names of the tiny bones are hammer, anvil and stirrup. 👀
T=3.42
V(speed)=1531m/s
By formula
V=d/t
1531=2d/3.42
1531×3.42=2d. Because by transposing method
5236.02=2d.
D=5236.02÷2
D=2663.01m
Bro 5236.02/2 = 2618.01
Sir, your videos really help me alot. Thanks alot sir😇

Sound wave is a mechanical wave because it needs a medium such as solid , liquid or gas to travel ,it can't travel in vaccum.
Sound waves are called mechanical waves because they need a medium to travel like solid, liquid and gas.
sound is a longitudnal mechanical wave
24:20 yes!
Thanks sir for this chapter because my exam is coming
You have cleared all my concepts of this chapter nd u r the best teacher of physics for me
