Explanation:
The question is incomplete because of the lack of a letter (with missing words that need to be filled in).
The question asks to give synonyms and antonyms to adjectives in a letter.
A synonym is a word that is similar to the word given (eg. small, tiny, minuscule, mousy).
An antonym on the other hand, is a word that means the opposite to the word given (small, big; finite, infinite; tall, short).
An adjective is simply a word used to describe a noun (any of the synonyms or antonyms mentioned above are adjectives).
Answer:
Statement that is true about electromagnetic and mechanical waves is:
Option B: Mechanical waves must travel through a medium, but electromagnetic waves do not require a medium to travel.
Explanation:
'Electromagnetic' waves do not need any medium to travel whereas 'mechanical waves' need a medium or matter for transmission. Electromagnetic waves are produced by the 'vibrations' of the charged particles. They can even travel in vacuum.
On the contrary, mechanical waves are caused by the 'wave amplitude'. Mechanical wave can travel in solid, liquid and gas and are considered to be periodic disturbance.
Thus, Option B is the most statement apt explaining the difference between electromagnetic and mechanical waves.
