Particles in a SOLID have a small amount of energy, vibrate, and are stuck in place?
It is important to note that the electromagnetic spectrum has a variety of wavelength and frequency of light in it. Some lights we can see, while others are not visual to our naked eye. It is actually very important to determine the kind of light as different lights have different wavelengths and frequencies. some lights are of very high frequency like the gamma rays, while others are of far lower frequency. <span />
Answer:
16.5 m
Explanation:
The following data were obtained from the question:
Time (t) = 0.1 s
Speed of sound in air (v) = 330 m/s
Distance (X) =?
The Lenght (i.e distance) of the room can be obtained as follow:
v = 2X / t
330 = 2 × X / 0.1
Cross multiply
2 × X = 330 × 0.1
2 × X = 33
Divide both side by 2
X = 33/2
X = 16.5 m
Thus, the length of the room is 16.5 m.
