Can you show the diagram please
Answer:
(A) 421 J energy stored in the capacitor for one flash.
(B) The value of capacitance is 0.0537 F
Explanation:
Given :
(A)
Time 
Average power 
W
From power equation,
So energy in one light is given by,
J
Since efficiency is 95 % so we can write, energy stored in one flash,
J
(B)
From the formula of energy stored in capacitor,
Where 
and 
V
Answer:
Although the speed changes and wavelength changes, the frequency of the light will be constant. The frequency, wavelength, and speed are related by: The change in speed that occurs when light passes from one medium to another is responsible for the bending of light, or refraction, that takes place at an interface.
Explanation:
The energy of a light wave is calculated using the formula
E = hc/λ
h is the Planck's constant
c is the speed of light
λ is the wavelength
For the ir-c, the range is
<span>6.63 x 10^-34 (3x10^8) / 3000 = 6.63 x 10 ^-29 J
</span>6.63 x 10^-34 (3x10^8) / 1000000 = 1.99 x 10^-31 J
For the ir-a, the range is
6.63 x 10^-34 (3x10^8) / 700 = 2.84 x 10^-28 J
6.63 x 10^-34 (3x10^8) / 1400 = 1.42 x 10^-28 J
