Why can you hear someone but not see them from another room?
You can hear the people speaking because sound waves are reflected off of other objects (walls, trees, etc.). When the waves are reflected, they can still make it to your position and allow you to continue hearing the people as they walk. Sound waves bend around the corner.
Give an exaple of a longitudinal and transverse wave?
A good example is vibrating guitar strings, as they are transverse, but the waves given off are sound, and sound is longtitude.
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine the speed of the object
If you shout into an empty bucket your voice bounces off the sides loudly this is called?
This is echo.
What is the similarity between echoes of sound and images in a mirror?
Echoes of sound and images in a mirror involves sound waves and light waves respectively being reflected off a surface.
What do you hear when sound bounces off the wall?
An echo
Why does sound off a mirror sound clearer than sound off a wall?
its a much harder surface and doesnt absorb the sound waves
Can you hear better in the rain?
Yes Sound waves bounce off walls
What property of sound allows you to hear sound waves around corners?
Because the sounds bounce off of walls.
How is it possible for you to hear someone who is talking around the corner from you?
Sound waves bounce off of walls and other objects, and so you can hear the wave because it is carried through matter. If you hold a guitar up to a wall, it becomes louder because the waves are being carried. Mostly, waves bounce off of walls. If there is no matter between two points to carry the wave, (for example in space) then the wave stops.
What can hear the best?
The bat. It can "hear" sound waves produced by it's own voice. The shape of the waves change when they bounce off obstacles, so the bat literally navigates by it's ears.

What is loudest sound in space?
There is no sound in space. There's nothing for sound waves to bounce off of. No one can hear you scream in space. Mwahaha. Just a little Halloween Joke there.
Does sound intensity change with distance?
Yes because the farther you are away the harder it is to hear. The sound will hit things and get caught in some but bounce off of others. if a sound keeps bouncing off of things then at some point the sound waves scatter and the sound disappears.
How do sound waves travel what do sound waves need in order to travel?
sound waves bounce off of walls. they need air to travel.
If a tree falls in the forest and no one is around to hear it does it make a sound What is ONE possible argument someone would make to agree OR disagree that a sound is indeed made?
Someone who agrees that a sound is made could argue that sound is a physical phenomenon that occurs regardless of human perception. The tree falling creates vibrations in the air which would be interpreted as sound waves if there were an observer present. Someone who disagrees might argue that sound is a subjective experience that requires an observer to perceive it. Without a listener to interpret the vibrations as sound, the falling tree may not technically produce a "sound" in the absence of human perception.
Does a reflection bounce off of a sound waves surface once the sound waves hit the surface?
no
