What is the energy of a photon of blue light with a frequency of 6.7 x 1014 hz?

6.626 x 10-34 js
9.9 x 10-49 j
4.4 x 10-19 j
1.0 x 1048 j

The relationship between energy and wavelength is shown by:

E = hc/wavelength

As we can see, there is an inverse relation between energy and the wavelength. Wavelength can be written in terms of frequency by the relation:

Frequency = c / wavelength

Therefore, the energy equation is simplified to:

E = h x frequency

E = 6.62607004 × 10^-34 J s x 6.7 x 10^14 /s

E = 4.44 x 10^-19 J

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
