You can't see beyond a blind turn, so a mirror would allow you to see around the corner.

Answer:
The waves will increase in frequency
Explanation:
As the young girl moves her hand back and forth faster, it will be observed that number of back and forth motions increase every second. Also the distance between crest and trough of the wave (wavelength) will be reduced as she moves her hand back and forth faster.
Frequency = number of turns (moves) per second
The waves will increase in frequency since there will be more number of back and forth motions in every second.
Also,
The distance between crest and trough will be reduced, which implies that there will be decrease in waves wavelength.
This can also be verified using wave equation;
V = Fλ
At constant velocity,
F ∝ ¹/λ
Thus, decrease in wavelength will cause increase in frequency of the waves.
The right answer is : The waves will increase in frequency

Answer:
Pressure, P = 3724 Pa
Explanation:
Given that,
Depth of water, 
Depth of oil, 
The density of water, 
The densinty of oil, 
We need to find the gauge pressure at the bottom of the cylinder. So, total pressure is equal to :
So, the gauge pressure at the bottom of the cylinder is 3724 Pa.
