16) how many photons are contained in a burst of yellow light (589 nm) from a sodium lamp that contains 609 kj of energy?
a) 3.37 × 1019 photons
b) 3.06 × 1030 photons
c) 1.81 × 1024 photons
d) 4.03 × 1028 photons
e) 2.48 × 1025 photons

 C) photons

Explanation:

E= energy = 609 kJ = 609000 J    (1kJ=1000J)

= number of photons = ?

h = Planck's constant  =

c = speed of light =

= wavelength of photon = 589 nm =

Putting values in above equation, we get:

Thus there are photons in a burst of yellow light (589 nm) from a sodium lamp that contains 609 kJ of energy.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
