Sir similarity is both are used for finding location. Difference is RADAR transmits electromagnetic waves but the SONAR produces sound wave for finding location.

Sir session was बल्ले बल्ले I like your teaching

[bhavibhashu]

Similarities of sonar and radar : both are used in finding the distance of the object by sending the signals which bounce back.

Difference of sonar and radar: radar uses uses radio waves which are a type of electro magnetic energy while sonar uses the method of echo in which it can detect the distance of the body from the submarine to the sea bed or it is also used to detect the objects under water.

I Hope it is the required answer ...

Sir ur explanation was something which is more than excellent.... please come up with some more videos
A bale bale from my side..

[sarojkachhawaha]

Waaah sir u r best teacher i want u to be in my school

[hiteshsura]

The world best lecture by the world best teacher

Homework
Similarities 👇
*SONAR stands for Sound Navigation and Ranging, and *RADAR stands for Radio Detection and Ranging. As their name suggests both are used for navigation and detection of different properties and attributes of objects. The waves are basically emitted from a source towards the object and once the waves strike the object they bounce back towards the source and are detected using detectors. This way the range and distance of the objects can be measured.

Differences 👇
They both use two fundamentally different waves for detection purposes. A RADAR uses radio waves or electromagnetic waves that do not require any medium to travel and SONAR uses ultrasonic or sound waves for detecting targets.

Best physics teacher ever had in my life

30:32 Both are sensor systems which use the transmission and reception of return signals to function. Radar systems operate using radio waves primarily in air, while sonar systems operate using sound waves primarily in water

[yasikarao]

I like ur teaching method now i like vendantu in vedantu u are very special for me abhishek sir is very special

[jiteshvara]

Your teaching is best in the world 🌎 🌎

[trinachakraborty]

Thank you so much sir aap mere favourite physics ke sir ho
Thank you so so much

[asthagupta]

U are very good teacher esehi videos banate rehna

[anushkachaturvedi]

Sir session was balle balle. I really enjoyed it a lot and ask what sir, once my first question goes wrong but after that, I learn from it and don't repeat that, and then my all numerical comes in a great way. THANK YOU SO MUCH, SIR, for such a great explanation

[Dheerajs]

Sir I want to ask that if we take speed of sound 344m/s so the distance will 17.2m and if we take speed of sound 340m/s so the distance will 17m, so can we say that 17.2m and 17m both are correct?
Pls reply.

[min_tae]

Sir, The session was veryyyy bigggg balle balle!

[thewatcher]

sir in 5:55 when two people talks in the same moment nd we are hearing it, that time we are able to little bit differentiate b/w what they both are talking about, does that means ki ye 0.1 mai jo reflection hoti hai vo ek particular sound wave ke liye hoti hai..

(edit 4-7-2021): Tysm for 13 likes, mere pehle comment mai itna support😅😅

[ilangovannatarajan]

Sir such a amazing teaching. One of my best teacher for physics

[shankarkarnal]

Sir u nailed this particular topic, , continue this a balle balle from my side

[deepakjain]

thank you somuch sir for helping me with physics😊
