Answer
we know,
where
E = energy
h = planks constant
λ = wavelength
from the above equation, we can see that energy is inversely proportional to wavelength.
that is why
Violet color light has low wavelength but the energy of Violet light is very high whereas red light has low energy and high wavelength.
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individualwaves upon the particles of the medium.Hope this help!
Answer:
KE = 10530 J or 10.53 KJ
Explanation:
The formula for kinetic energy is KE = 1/2 mv^2
Let's apply the formula:
KE = 1/2 mv^2
KE = 1/2 (65kg) (18m/s)^2
KE = 10530 J or 10.53 KJ
