(physics question)why our sound is able 2 be heard in another room while our image our light cant?

Question

sound n light both r in a form of energy but why our sound can be heard in another room while light cant sum1 explain it in easy way according 2 d caliber of a 10 grader

Answer 1

Light and sound are both vibrations that travel through space as waves. They are, however, different.

Sound is a vibration of some medium that it travels through, like air or water. Sound vibrations travel through air by compressing the air, then rarefying the air, compressing the air, then rarefying... "If there is no medium to vibrate," says Hewitt, "then no sound is possible."

Light is a vibration of magnetic and electric fields--a vibration of pure energy.

As you know, light waves can pass through many media: air, water, glass, to name a few. But they do not need any medium. Sunlight, moonlight, and starlight pass through the vacuum of outer space to reach us.

The source of all waves is something vibrating. The vibrating prongs of a tuning fork generate a sound. Vibrating electrons in an atom generate light. The basic difference between sound and light travel is that sound requires an intervening substance to change and impose a wave pattern on. Whereas light does not. Sound travel is motion; light travel is radiation. Light is influenced by shadows unlike sound, that is why light cannot penetrate through an opaque wall.

Answer 2

nice question...better phrased as why sound can travel through an opaque wall, but light cannot...

assuming walls are not of an insulative nature, sound will be heard from an adjascent room as sound needs such media to be propagated. light needs no such media(it can travel through a vacuum), but its kind of energy is easily absorbed by different media and/or converted to other forms of energy, not perceived as light.

the physics behind why sound can do that yet light cannot is a factor of the lattice or molecular composition of material through which either has to traverse.

opaque objects' molecular structure absorbs light energy and/or convert to other forms of energy and/or reflect the light back.

sound travels through an opaque wall (assuming walls are not of insulative nature) as sound energy is actual physical vibration of media, which can be propagated to any media that are in contact and can vibrate.

sound also has a very long wavelength wrt light, hence easily refracted. it therefore is not as directional as light which has a very short wavelength.

sound therefore does not need to travel in a 'straight line' to reach perceiver, light does

Answer 3

Sound can travel through walls.  Light can't.

Also, sound is just a simple wave.  An image is formed by many individual beams of light, all different colours and strengths.  If the direction of some of those beams is changed, then the resulting image will be distorted  (think bathroom windows).
