Answer: The light is slowed down by the prism, but the different wavelengths of light are all slowed down a different amount by the prism.
Explanation:
What happens here is that white light passes from a medium with an specific index of refraction (air) to another medium with a different index of refraction (the material of which the prism is composed).
Then, when light passes from a medium to another, its speed changes causing the deviation of the beam of light. However, we are talking about white light that is composed of different wavelenghts. So, since the frequency of light remains costant when passing from one medium to another, the different wavelengths change as a result of the change in speed.
This was first observed by Isaac Newton in the eighteenth century, when he found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors.
Explanation:
The speed of rotation of Venus is slower than that of Earth that is why a day on Venus is longerthan Earth's day. Whereas, Venus is closer to sun than Earth, this means Venus trajectory of revolution is smaller than that of Earth.Therefore, a year on Venus is shorter than Earth's year.
Answer:
38Kgm/s
Explanation:
Momentum (p) = mass (m) × velocity (v)
Total momentum is the sum of all the momenta of each object in a system. That is:
Total momentum = {m1v1} + {m2v2}
Where;
m1 = mass of ball 1 = 5kg
v1 = velocity of ball 1 = 4m/s
m2 = mass of ball 2 = 6kg
v2 = velocity of ball 2 = 3m/s
Total momentum = {5 × 4} + {6 × 3}
Total momentum = {20} + {18}
Total momentum = 38Kgm/s
To solve this problem it is necessary to apply the concepts related to Period in a spring, elastic potential energy and energy in simple harmonic movement.
From the definition we know that the period can be expressed as
Where
m= Mass
k = Spring constant
Our values are given as
m = 16.6Kg
K = 2470N/m
Therefore the period would be
PART A) The frequency is the inverse of the period therefore
PART B) Elastic potential energy depends on compression and elasticity therefore
PART C) Kinetic energy depends on mass and speed therefore
PART D) As energy is conserved, the total energy is equivalent to the dual ratio of the elasticity constant and the amplitude, mathematically,
Therefore the motion's amplitude is 1.07m
