5 m and below
a closed room
a hill station
Sound travels faster in
Solids
Liquids
Gases
Vacuum
We cannot be able to hear anything in vacuum because
there is no gravity
there are many asteroids
of the absence of air particles
of the height we are from the earth

Metal flaw detection
If the particle vibrates parallel to the direction of the propagation of the wave such a wave is called as
Electromagnetic Wave
Mexican Wave
Transverse wave
Longitudinal Wave
Observe the images and pick the odd one out
Speed of the sound wave is obtained by the formula_______
v = f x λ
v = f x t
f = v x d
λ = v x f
More the amplitude ________________ the sound
softer
louder
quieter
none of these
