Compact fluorescent bulbs because they made out of glass that will break and will dye and then they can't be used again
Be more specific with the question
Answer:
f = 1.37 × 10¹⁵ Hz
Explanation:
Given data:
Energy of photon = 9.08 × 10⁻¹⁹ j
Frequency = ?
Solution:
Formula:
E = h. f
f = frequency
h = planck's constant
E = energy
Now we will put the values in formula.
h = 6.63 × 10⁻³⁴ j.s
9.08 × 10⁻¹⁹ j = 6.63 × 10⁻³⁴ j.s × f
f = 9.08 × 10⁻¹⁹ j / 6.63 × 10⁻³⁴ j.s
f = 1.37 × 10¹⁵ s⁻¹
s⁻¹ = Hz
f = 1.37 × 10¹⁵ Hz
