Description : Which waves cannot be transmitted through vacuum - (1) Light (2) Heat (3) Sound (4) Electromagnetic
Last Answer : (3) Sound Explanation: Sound waves cannot be transmitted through vacuum. It is transmitted by the movement of particles along with the direction of the motion of the sound wave. More generally, sound is a mechanical disturbance which is dependent upon a medium to travel.

Last Answer : (1) de Broglie waves Explanation: In mechanics, matter waves or de Broglie waves reflects the wave-particle duality of matter. The de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle and is also called de Broglie wavelength.
Description : These waves cannot be trans-mitted through vacuum – (1) Light (2) Sound (3) Heat (4) Electromagnetic
Last Answer : (2) Sound Explanation: Sound is a mechanical wave that is created by vibrating objects and propagated through a medium from one location to another. Because mechanical waves rely on particle interaction ... space that are void of particles. That is, mechanical waves cannot travel through a vacuum.
