If you had four blue cards, four red cards, and four yellow cards in a deck, what are the chances of drawing a blue card on your first try? 1/4
1/12
1/16
1/3

Total cards = 12 cards

Total Blue cards = 4

Ratio probability = 4/12 = 3

You have a 30% chance.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
