A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will _____ the wavelength. a 100
1 answer:
The correct answer is "decrease":
<span>A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will INCREASE the wavelength.
Let's see why. The basic relationship between frequency and wavelength of a wave is
</span>
<span>where
v is the speed of the wave
f its frequency
</span>
its wavelength
<span>
We can see from this equation that, if the frequency is increased, if the speed of the wave does not change (and this is the case), then the wavelength of the wave must decrease, since the ratio </span>
becomes smaller.

Explanation:
The relationship between force applied on a string and stretching of the spring is given by Hooke's law:
where
F is the force exerted on the spring
k is the spring constant of the spring
x is the stretching of the spring from its equilibrium position
In this problem, we have:
F = 20 N is the force applied on the spring
k = 140 N/m is the spring constant
Solving for x, we find how far the spring will stretch:
