What is the wavelength of a wave with a frequency of 0.4 kHz traveling at 16 m/s?
larisa86 [58]

Answer: 0.04metres

Explanation:

The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ

Recall that Velocity (V) = Frequency F x wavelength λ

V = F λ

Make λ the subject formula

λ = V / F

In this case Frequency = 0.4 kHz

Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz

Velocity of wave = 16 m/s

So, λ = V / F

λ = 16 m/s / 400Hz

λ = 0.04metres

Thus, the wavelength of a wave is 0.04metres

What determines the viscosity of magma? What else determines whether a volcano will erupt violently or calmly 
mr Goodwill [35]

The viscosity of magma is determined by its silica content. Basalt magma, on the one hand, which is often of low viscosity, has a low silica content of approximately 50% or less. Rhyolite magma, on the other hand, has high viscosity due to the high silica content of approximately 70% and more.

Gas content and temperatures of the magma are the other factors that determine an explosive or nonexplosive eruption. High temperatures and high gas content (coupled with high viscosity) cause violent explosions.
