Answer:
Explanation:
Given
de Broglie wavelength = 0.20nm
Required
Determine the speed (v)
The speed is calculated using the following formula;
Where
Substitute these values in the above formula
-----------------------------------------------------
Convert 0.2nm to metre (m)
-----------------------------------------------------
Multiply both sides by v
Apply law of indices
Divide both sides by
Apply law of indices
Hence;
The velocity is
The wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
Answer:
Explanation:
As we know that speed of a wave is directly proportional to the product of wavelength and frequency of the wave. If any two variables are known, then we can easily find the third parameter.
Like, in this case, the wavelength is not given, instead the frequency is given as 4 Hz and speed is given as 2 m/s, so the wavelength can be easily determined.
Speed = Wavelength × Frequency
Then Wavelength = speed/frequency
So, wavelength = 2/4=0.5 m
Thus, the wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
