The wave interaction that is shown in the photo is refraction as light moves from air to water.
<h3>What is refraction?</h3>
Refraction refers to the change in the frequency of a wave and the direction of the wave as it moves from one medium to another. We know that waves makes a body under water to look slightly different than when it is in air.
Thus, the wave interaction that is shown in the photo is refraction as light moves from air to water.

Answer:
The first overtone frequency is 100 Hz.
Solution:
According to the question:
Length of pipe, l = 1.75 m
Speed of sound in air, v_{sa} = 350 m/s
Frequency of first overtone, 
is given by:
Since, the frequency, as clear from the formula depends only on the speed
and the length. It is independent of the air temperature.
Thus there will be no effect of air temperature on the frequency.

Answer:
Biosphere is the part of the earth where life exists.
Answer:
Sound energy wave is transferred through a substance as a series of compressions.
Explanation:
Sound is caused by regular oscillating that produce regions of compression (high pressure) and rarefaction (low pressure) that move through a substance. Sound not only travels through air, it can travel through any substance, solid, liquid or gas. Whales can hear other whales across whole oceans through water, an Earthquake is low frequency sound moving through the solid Earth
A vibrating object compresses the air and sound waves move from the source, much like waves in water if you drop a stone into it. These sound waves can carry great distances depending on their loudness and frequency.
