A sound wave in a solid has a frequency of 15.0 kHz and a wavelength of 0.333 m. What would be the wave speed, and how much faster is this speed than the speed of sound in air?

L = V/F = 0.333 m.

L = V/15000 = 0.333
V = 0.333 * 15,000 = 4995 m/s.

4995 - 343 = 4652 m/s faster.

Well, isn't that a hard-rockin' sound wave! To find the wave speed, we can use the formula:

Wave speed = frequency x wavelength

Plugging in the given values, we have:

Wave speed = 15.0 kHz x 0.333 m

Now, converting kilohertz to hertz, we have:

Wave speed = 15,000 Hz x 0.333 m

That gives us:

Wave speed = 4,995 m/s

Wow, that sound wave is moving pretty fast! But how does it compare to the speed of sound in air? Get ready for a punchline because it's gonna sound like a joke:

It's faster. No, really, it is!

The speed of sound in air is generally around 343 meters per second (yes, that's right, I actually have some serious facts up my sleeve). So, comparing the two speeds, we find that the sound wave in the solid is whoppingly faster than the speed of sound in air!

To find the wave speed, we can use the formula:

Wave Speed = Frequency × Wavelength

Given that the frequency is 15.0 kHz (kilohertz) and the wavelength is 0.333 m, we can substitute these values into the formula to calculate the wave speed:

Wave Speed = 15,000 Hz × 0.333 m

Wave Speed = 4,995 m/s

Therefore, the wave speed in the solid is 4,995 meters per second.

To determine how much faster this speed is than the speed of sound in air, we need to know the speed of sound in air. Typically, the speed of sound in air at room temperature is approximately 343 meters per second.

Calculating the difference in speed:

Difference in Speed = Wave Speed in Solid - Speed of Sound in Air

Difference in Speed = 4,995 m/s - 343 m/s

Difference in Speed ≈ 4,652 m/s

Therefore, the wave speed in the solid is approximately 4,652 meters per second faster than the speed of sound in air.

To calculate the wave speed, we can use the formula:

Wave Speed = Frequency × Wavelength

Given:
Frequency = 15.0 kHz = 15,000 Hz
Wavelength = 0.333 m

Substituting the values into the formula, we get:

Wave Speed = 15,000 Hz × 0.333 m

Multiplying these values, we find:

Wave Speed = 4,995 m/s

Therefore, the wave speed of the sound wave in the solid is 4,995 m/s.

To compare this speed with the speed of sound in air, we need to know the speed of sound in air. The speed of sound in air at room temperature is approximately 343 m/s.

Calculating the difference between the wave speed in the solid and the speed of sound in air:

Difference = Wave Speed in Solid - Speed of Sound in Air
Difference = 4,995 m/s - 343 m/s

Subtracting these values, we find:

Difference = 4,652 m/s

Therefore, the speed of the sound wave in the solid is approximately 4,652 m/s faster than the speed of sound in air.
