EleoNora [17]3 years ago
8 0

Answer:

(I)

{ \bf{ {v}^{2} =  {u}^{2}  - 2as }} \\  {v}^{2}  =  {0}^{2}  - (2 \times 0.5 \times 5) \\  {v}^{2}  = 5 \\ { \tt{final \: velocity = 2.24 \:  {ms}^{ - 1} }}

(ii)

{ \bf{v = u + at}} \\ 2.24 = 0 + (0.5t) \\ { \tt{time = 4.48 \: seconds}}

Photons with the highest energy have the ____
Setler79 [48]

Answer:

D. shortest wavelength

Explanation:

Photons with the highest energy have the shortest wavelength. The shorter the wavelength, the higher the energy of a photon.

A photon is a quantity that transmits electromagnetic energy from one place to the other.

  • Gamma rays have photons that transmits the highest amount of energy.
  • The rays have the shortest wavelength and highest frequency of all electromagnetic radiations.

Energy, wavelength and frequency of a photon are connected using the expression:

    E =  h f  = \frac{hc}{wavelength}  

E is the energy

h is the Planck's constant

 f is the frequency.
