Answer:
the correct answer is C v = 60 cm / s
Explanation:
The speed of a wave is related to the frequency and the wavelength
v = λ f
They indicate that the object performs 20 oscillations every second, this is the frequency
f = 20 Hz
the wavelength is the distance until the wave repeats, the distance between two consecutive peaks corresponds to the wavelength
λ = 3 cm = 0.03 m
let's calculate
v = 20 0.03
v = 0.6 m / s
v = 60 cm / s
the correct answer is C
Answer:
25 seconds!
Explanation:
I just had to find what number to multiply 4 to get 100 and it was 25
4x25=100
Or you could do the easier way by dividing 100 by 4 which has the same answer: 25
100÷4=25
Answer:
An increase in frequency
Explanation:
A photon is an electromagnetic radiation without mass,as the energy of a photon is increased it frequency also increases.
Consider the equation below.
Energy = hf
We're h= is the Planck constant.
F is the frequency measured in Hertz from this a direct relationship exist between the energy and frequency
