Answer:
Explanation:
Given
Altitude from which Diver steps out 
altitude at which diver opens the Parachutes 
total height covered by diver
Initial velocity of diver is zero
using equation of motion
where s=displacement
u=initial velocity
a=acceleration
t=time
Answer:
White light is the combination of all colors of the spectrum.
Answer: 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.
