A) E=hc/wavelength where h =6.620*10^-34 Js c=3*10^8 m/s E in joules

B) E=h*frequency frequency in Hz Hz=1s^-1

C) wavelength = c/frequency results in m

D) same as c

E ) wavelength = hc/E

F) and G) I never used RH and do not know what it is

in actuality ,in simple terms,gentle is a micro mass possessing a particular volume. This volume of light strikes on the cost of light; So the size of return and forth in step with oscillation of one micro mass of light is comparable to the made of the era of oscillation and the cost of light. The micro hundreds of light permeate the universe till a number of its radiation is absorbed via a Celestial physique. even although gentle never get away the Gravitational field of the Universe. So while gentle reaches the form horizon of the Universe it is going to proceed to be restrained in the quantity of its containment. the clarification why this occurs is that the Universe purposes a conservative gadget.
