Question

why transverse waves cannot be produced in liquid and gas??? no spam.want my answer with explanation ...

Answer 1

The particles in transverse waves move perpendicularly to the direction of propagation so it cannot propagate in a gas or a liquid because there is no mechanism for driving motion perpendicular to the propagation of the wave. ... Trasverse waves (light) is produced and passed through gas and water.

Answer 2

EXCERPT FROM WIKIPEDIA:First let's see how transverse waves or S-Waves propagate, so in simple terms we can state that, S-Waves or transverse are shear waves, whose particles move perpendicularly to their direction of propagation.

Now, let's see why can they propagate through solids. They can propagate through solid because solids have enough shear strength. The shear strength is one of the forces that hold the solid together, and prevent it from falling apart.

The case with liquids is that, liquids do not have that much shear strength: for example consider this, if you take a glass of water and suddenly, somehow you remove the glass, the water will not keep it's shape and will just flow away. So in fact it just boils down to the fact that transverse-waves need a medium rigid enough to propagate, which liquids can't provide.

Also remember that not all transverse waves require a rigid medium to travel. Transverse waves can also travel along the surface tension of the ocean, creating water waves. Light and electromagnetic waves are also transverse waves, however they are self-propagating, meaning that they sustain themselves due to the magnetic field they create, and thus can travel through a vacuum, only slowing down slightly when passing through water or air.
