Speed of sound (v) in a medium is related to its frequency (v) and wavelength (λ) as :
(a) Correct relation is v = v × λ https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-11/

See lessWhat jump size will let Jumpy land on both 15 and 30?
To find the suitable jump size we need a figure that is also a factor to both 15 and 30. The factors of 15 are 1, 3, 5, and 15. For 30 these are 1, 2, 3, 5, 6, 10, 15, and 30. Shared factors are all 1, 3, 5 and 15 and from the presented options, our choice is going to be number 5. Click here for morRead more
