Blue light will bend more than the others because it has a slightly greater refractive index. This is because blue light has a shorter wavelength and more energy, meaning it has to slow down more than the others when it hits the water.
Answer:
honestly i dont like physics class but for you im gonna write somethin' good but for me tho its B O R I N G
Explanation:
<em>Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.</em>
There is no apparatus for it. It is either use something like ruler and table and rub together or rub our hands, and friction force will be showed.
Answer:
i have no idea what this is
Explanation:
Explanation:
It is given that,
Fundamental frequency, f = 220 Hz
(a) We know that at 0 degrees, the speed of sound in air is 331 m/s.
For open pipe, 
l is the length of pipe
Also,
(b) Let f' is the fundamental frequency of the pipe at 30 degrees and v' is its speed.
v' = 348.71 m/s
So, 
f' = 232.4 Hz
Hence, this is the required solution.
