Answer: contain different amounts of energy
Explanation:
The energy of a photon is given by:
Where:
is the Planck constant
is the frequency of the light which is inversely related to the wavelength.
Now, if we have photons of different light waves, this means we have photons with different frequencies.
As the energy of the photon depends on its frequency:
Photons of different light waves <u>contain different amounts of energy.</u>
Answer:
Distance, d = 112.5 meters
Explanation:
Initially, the bicyclist is at rest, u = 0
Final speed of the bicyclist, v = 30 m/s
Acceleration of the bicycle,
Let s is the distance travelled by the bicyclist. The third equation of motion is given as :
s = 112.5 meters
So, the distance travelled by the bicyclist is 112.5 meters. Hence, this is the required solution.
