Answer:
A. -10,000
Explanation:
When x approaches zero, the graph tells us that F(x) either becomes extremely large or extremely small. The best answer is therefore A: -10,000. Best, because we aren't given the exact value of x, but clearly the other results require that x be greater than 1 or less than -1, which is far from zero.
According to Einstein the energy of photon is given by the equation,
E = hν = h . c/λ
where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.
Given, wavelength = 608 nm = 608 x 10⁻⁹ m
Conversion factor: 1 nm = 10⁻⁹ m
c = 3 x 10⁸ m/s
h = 6.626× 10⁻³⁴ J.s
Substituting the data into the equation we get,
E = h . c/λ
E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m
E = 3.27 x 10⁻¹⁹J
3.27 x 10⁻¹⁹J energy must be added to strontium to get it to produce 608 nm wavelength.
