Answer:
v = 2.2 * 10^(-24) m/s
Explanation:
Momentum is given in terms of wavelength as:
p = h/λ
Where h is Planck's constant = 6.626 * 10^(-34) kgm²/s
Hence, momentum will be:
p = 6.626 * 10^(-34) / (5.4 * 10^3 * 10^(-10)
p = 1.23 * 10^(-27) kgm/s
For a 56.7 g ball to have the same wavelength as green light, they must have the same momentum.
Momentum is given in terms of mass as:
p = m*v
p = 0.0567 * v
1.23 * 10^(-27) = 0.0567 * v
v = 1.23 * 10^(-27) / 0.0567
v = 2.2 * 10^(-24) m/s
Hence, it would have to move at a speed of 2.2 * 10^(-24) m/s to have the same wavelength.
It is not an example of kinetic to potential because the dog is already in motion rather then having the potential to do something. Hope this helps!
Answer:
Explanation:
We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as where v is speed of light is frequency of light is wavelength of light
In first case we have given λ=655 nm
so using formula
Hz
In second case we have wavelength 515 nm so by using above formula
In third case we have wavelength 475 nm
so
