The event that happens to sound waves from an object as it moves toward you is The pitch gets higher because of an increase in wavelength.
<h3>What is sound waves?</h3>
Sound waves refer to a form of transverse wave that compress and vibrate while travelling from one medium to another thereby transferring energy.
Therefore, The event that happens to sound waves from an object as it moves toward you is The pitch gets higher because of an increase in wavelength.

'Acceleration' is any change in the speed or direction of motion.
Now that we ( I ) have that definition clear, we can look through
the choices:
A). \
B). > No. Neither speed nor direction changed.
C). /
D). Yes. The boy's direction changed.
Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
