Answer:
See explanation.
Explanation:
Let us go through each of statements one by one.
Light waves may travel either through a transparent medium or through empty space.
Yes, light travels through empty space as well as through transparent media, however, in the latter its speed is slowed down.
Sound waves travel through all substances.
Sound waves are vibrations in a medium. All substances can vibrate; therefore, sound travels through all substances.
Light waves are absorbed and reflected by opaque materials so that no light travels through them.
This is true. The reason light does not pass through an opaque substance is because it is absorbed or reflected way from us.
Light waves cannot travel through empty space.
No, <em>electromagnetic radiation can travel through empty space</em> because it is not a disturbance in a medium.
Sound waves do not require a medium for traveling,
Nope. Sound waves are disturbances in a medium—they cannot exist independent; therefore, they require a medium for travelling.
Sound waves can only travel through transparent objects
No. Sound waves travel through all substances that can vibrate.
Sound waves require a medium for traveling,
As sound waves are vibrations in a medium, they need medium in which they can exist and travel.
