Mechanical waves waves need to interact with particles of either a solid, liquid, or gas to travel.
<u>Explanation:</u>
In the world, the dispersal of energy is under the control of two important waves called electromagnetic waves and mechanical waves. Waves in water and sound waves in air are two instances of mechanical waves. Mechanical waves are brought about by an unsettling influence or vibration in particles of either a solid, liquid, or gas to travel.
Water waves are formed by vibrations in a fluid and sound waves are shaped by vibrations in a gas (air). These mechanical waves travel through a medium by making the atoms to interact with one another.
Answer:
No, bats are not blind. Bats have small eyes with very sensitive vision, which helps them see in conditions we might consider pitch black. They don't have the sharp and colorful vision humans have, but they don't need that.
Explanation:
1. Establish routines. Young children thrive on them, and they make perfect fodder for enhancing your child's memory.
2. Play memory games. Ask questions when you're out and about. For example, if you're passing a friend's house, ask, "Who lives there?" Games like this give children experience in recalling information.
3. Demonstrate how to perform tasks. Babies model their parents' actions. If you want your child to learn how to do something, such as stack one block on another, show him how and then give him a turn.
4. Talk with your child about her experiences. Focus on events that resonated strongly with her, such as a trip to the zoo. As she gets a little older, help her make stories out of her recollections.
