Question

when the particles of a medium are vibrating perpendicular to the direction of the energy of the wave, then the wave is a ______ wave. a light b electromagnetic c longitudinal d transverse

Explanation:

To solve this, we recall wave types:

• Transverse waves: Particles vibrate perpendicular to wave energy direction.
• Longitudinal: Parallel. Light and electromagnetic waves are transverse (but the option here with the correct type description—wait, the options seem to have a typo? Wait, maybe the last option is "transverse". Wait, the given options: a) light, b) electromagnetic, c) longitudinal, d) (maybe "transverse"). Wait, the question is about particle vibration perpendicular to wave direction. Transverse waves have this. But among the options, maybe there's a typo, but if we check: Longitudinal is parallel, so c is wrong. Light and electromagnetic are transverse, but the question's blank—wait, maybe the correct option is d (if d is transverse). But maybe the original options had a typo, but assuming d is "transverse", that's the answer. Wait, maybe the user's image has d as "transverse". So the correct answer is the one where particles vibrate perpendicular, which is transverse (so d, if d is transverse).

Answer:

d. transverse (assuming d option is "transverse" as the correct term for waves with particle vibration perpendicular to wave energy direction; longitudinal is parallel, light/electromagnetic are types of transverse but the question is about the wave type based on particle motion, so transverse is the category here)
