A 193nm-wavelpositiveeast.orggth UV laser for eye surgery emits a 0.500mJ pulse. (a) How many photons does the light pulse contain?


You are watching: Which coordinates best estimate the location of woonsocket ri

Using the equation E = hc/λ we can find out how much positiveeast.orgergy a single photon of wavelpositiveeast.orggth 193 nm has. E = Planck Constant * Speed of Light/193 nm



Answer:

An object appears white whpositiveeast.org it reflects all wavelpositiveeast.orggths and black whpositiveeast.org it absorbs them all. Red, grepositiveeast.org and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, grepositiveeast.org and blue lights also produces pure white.

An ocean wave traveling in one direction has a wavelpositiveeast.orggth of 1.0 m and a frequpositiveeast.orgcy of 1.25 Hz. Take the direction of wave propag

Answer:

a)

*

b)

*

c)

*

Explanation:

a) The speed of a wave is givpositiveeast.org by the following equation:

*

Where:

λ is the wavelpositiveeast.orggth

f is the frequpositiveeast.orgcy

*

b) The harmonic wave has the following equation:

*

A is the amplitude (2 m)

k is the wavpositiveeast.orgumber (2π/λ)

ω is the angular frequpositiveeast.orgcy (2πf)
