A transverse wave may, or may not, be a mechanical wave (electromagnetic waves are also transverse).I don't know about congressional waves; you may want to ask a representative of congress in your country.
transverse waves.
Because the theory is that this is what the form is. If it were a longitudinal or compressional form (such as sound) it would need to travel through a medium of some sort to compress the particles of that medium. But electromagnetic radiation can travel even in a vacuum.
Sound wave is a mechanical wave. It means that, for propagation, it badly needs a material medium. But, light waves are not mechanical waves. They are electromagnetic waves. It does not need a material medium. It can pass even through vacuum. Sound wave is longitudinal in nature where as light waves are transverse in nature. Being transverse, light can be polarized. But, sound waves being longitudinal cannot be polarized.
Longitudinal and transverse are both
No. Radio waves are a type of electromagnetic waves; electroctromagnetic waves are transverse waves.
transverse and longitudinal
transverse and longitudinal
It is not so much longitudinal vs. transverse - it is the type of wave. Mechanical waves, by definition, travel through matter. That includes sound waves. Mechanical waves, however, can be both longitudinal and transverse - and both require a medium.
transverse waves.
X- rays are transverse waves!x rays are electromagnetic waves and transverse .
X-rays are a type of electromagnetic waves; electromagnetic waves are transverse waves.
Transverse / Electromagnetic depending on the context of the question
Transverse waves only travel through solids. These are also known as S waves.
Examples of transverse waves would be light waves, seismic waves or any other type of electromagnetic wave.
Sound waves are longitudinal in nature, and they require a medium for propagation.
