Sound waves are known to be the one that's not considered as a type of electromagnetic energy. As for microwaves and x-rays, they tend to share the same frequencies that can be considered as electromagnetic, and sound waves have a different frequency than them.
Constellations are based off of many Greek and Roman fables. Many of their gods and beliefs are pictured in the stars, which is where we get most of our constellations. Hope this helps!
That would be 110/22, which is 5 hours
Answer:
The answer and explanation is in the attached file
Answer: in air 33.33 ps and in the glass 50 ps: so the difference 16.67 ps
Explanation: In order to calculate the time for a pulse travellin in air and in a glass we have to consider the expresion of the speed given by:
v= d/t v the speed in a medium is given by c/n where c and n are the speed of light and refractive index respectively.
so the time is:
t=d/v=d*n/c
in air
t=0.01 m*1/3*10^8 m/s= 33.33 ps
while for the glass
t=0.01 m*1.5* 3* 10^8 m/s= 50 ps
Finally the difference is (50-33.33)ps = 16.67 ps
