Answer:
4 Hz
5 m
1 m
20 m/s
Explanation:
The first part of the sentence describes the frequency of the wave i.e., the number of oscillations every second
f = 4 /s = 4 Hz
The second part of the sentence describes the wavelength or period of the wave i.e., the distance between successive crests or troughs.
λ = 5 m
The last part of the sentence describes the peak to peak amplitude of the wave i.e., the height between the lowest part to highest part of the wave
The peak amplitude is given by
The velocity of a wave is given by
v = fλ
⇒v = 4×5
⇒v = 20 m/s
The velocity of the wave is 20 m/s
Answer:
Wavelength = 1.36 * 10^{-34} meters
Explanation:
Given the following data;
Mass = 0.113 kg
Velocity = 43 m/s
To find the wavelength, we would use the De Broglie's wave equation.
Mathematically, it is given by the formula;
Where;
h represents Planck’s constant.
m represents the mass of the particle.
v represents the velocity of the particle.
We know that Planck’s constant = 6.6262 * 10^{-34} Js
Substituting into the formula, we have;
Wavelength = 1.36 * 10^{-34} meters
