1. If the period of a wave is 0.27s, how many waves would pass by in 1.0 minute?
2. When a wave from of light passes through an opening that's large compared to its wavelength, it:
a) behaves as a single new point source
b) produces a straight wave front, curved backwards at the ends
c) produces spherical patterns of waves
d) none of the above
1. 60s. * 1Wave/0.27s. = 222 Waves.
1. Well, if the period of a wave is 0.27 seconds, then we can find out how many waves pass by in 1 minute. Let me mathematically juggle this for you... Okay, here it is. There are 1/0.27 waves passing by in one second. And since there are 60 seconds in a minute, you'll have 60 times of that. So, the total number of waves passing by in 1 minute would be... drum roll, please... approximately 222.222 waves! I hope you can catch them all!
2. Ah, light waves and their mischievous behavior! When a wave from of light passes through an opening that's large compared to its wavelength, it doesn't behave like a well-mannered citizen. Nope, it doesn't become a single new point source like someone reinventing themselves after a bad haircut. It also doesn't produce a straight wave front, curved backwards at the ends like someone trying to casually show off their flexibility. And you know what? It definitely doesn't produce spherical patterns of waves like some abstract artist gone wild. So, the answer is none of the above! Light waves, you just can't predict their fashion choices!
1. To find out how many waves would pass by in 1.0 minute, we need to determine the frequency of the wave first.
Frequency (f) is the reciprocal of the period (T) of a wave. So, f = 1 / T.
Given that the period of the wave is 0.27s, we can calculate the frequency as follows:
f = 1 / T = 1 / 0.27s ≈ 3.70 Hz
Now, to find the number of waves passing by in 1.0 minute, we multiply the frequency by the time in seconds:
Number of waves = frequency × time = 3.70 Hz × 60s = 222 waves
Therefore, approximately 222 waves would pass by in 1.0 minute.
2. When a wave of light passes through an opening that's large compared to its wavelength, it produces spherical patterns of waves. So, the correct answer is C) produces spherical patterns of waves.
1. To find out how many waves would pass by in 1.0 minute, you need to know the frequency of the wave. Frequency is the reciprocal of the period, which means it is the number of waves per unit of time. In this case, the period is given as 0.27s, so the frequency would be 1 / 0.27 = 3.70 waves per second.
To find out how many waves would pass by in 1.0 minute, you would multiply the frequency by the number of seconds in 1 minute. Since there are 60 seconds in 1 minute, the calculation would be:
Number of waves = frequency * time
Number of waves = 3.70 waves per second * 60 seconds
Number of waves = 222 waves
Therefore, in 1.0 minute, 222 waves would pass by.
2. When a wave of light passes through an opening that's large compared to its wavelength, it produces spherical patterns of waves.
The phenomenon you are referring to is called diffraction. Diffraction occurs when a wave encounters an obstacle or opening that is comparable in size to its wavelength. When light passes through an opening that is large compared to its wavelength, it spreads out in a phenomenon called diffraction, creating a spherical pattern of waves.
So, the correct answer is c) produces spherical patterns of waves.
