Given:
E = 7.3 × 10–17 Hz
h= 6.63 × 10–34 J•s
Now <em>E = hf</em>
where E is the energy of the photon
h is the Planck's constant
f is the frequency of the photon
Substituting the values in the equation we get
E= 7.3 × 10^-17 × 6.63 × 10^-34
<u>E= 4.8399 × 10^-50 J. </u>

Answer:
x = 7
Explanation:
Simplifying
11x + 13 = 12x + 6
Reorder the terms:
13 + 11x = 12x + 6
Reorder the terms:
13 + 11x = 6 + 12x
Solving
13 + 11x = 6 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
13 + 11x + -12x = 6 + 12x + -12x
Combine like terms: 11x + -12x = -1x
13 + -1x = 6 + 12x + -12x
Combine like terms: 12x + -12x = 0
13 + -1x = 6 + 0
13 + -1x = 6
Add '-13' to each side of the equation.
13 + -13 + -1x = 6 + -13
Combine like terms: 13 + -13 = 0
0 + -1x = 6 + -13
-1x = 6 + -13
Combine like terms: 6 + -13 = -7
-1x = -7
Divide each side by '-1'.
x = 7
Simplifying
x = 7
Answer:
3.75 * 10^14
Explanation:
(3.0 * 10^17) / 800nm = 3.75 * 10^14hz ( have to have 17 and not 8 because its in nanometers)
