Answer:
Blue light has the higher frequency.
Explanation:
Remember that the relation between wavelength and frequency for any electromagnetic wave in the vacuum is
where is the speed of light in the vacuum. As you can see, the relation between frequency and wavelength is inversely proportional. The higher is the wavelength, the lower is the frequency.
We know that in physics the momentum of an object is defined as the product of mass by the velocity of the object.
That is to say:
Where P is the momentum = kilograms meters/second
m is the mass
v is the object velocity = 30 m/s
In this problem we have the momentum of the roller coaster and its speed, but we want to find its mass. Then we divide the momentum between speed.
The mass is 833.33 kg
