The energy of a photon is e=\frac{hc}{\lambda}e = h c λ where c is the speed of light and h is a constant known as planck's constant. if a red photon has twice the wavelength of a violet photon, then the energy of the red photon is the energy of the violet photon. this shows that short-wavelength photons carry proportionally energy than long-wavelength photons.

As a red photon has a twice of the wavelegth to the violet photon then the red photon has half energy of the violet photon.

Explanation: In order to explain the above statement we have to consider the Plack postulate where the energy of photons depend directely of the frequency . As the wavelength and frequency are related by :

c= λ*υ c is the speed of light,  λ is the wavelength and υ the frequency of the photon

so the energy of  photons are inversely proportional to the wavelength.

As a consequence twice wavelengtht means half energy for the photon.  

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

pe = weightxheight = 2000x1000=2,000,000joules
