A laser is used in eye surgery to weld a detached retina back into place. The wavelength of the laser beam is 611 nm, while the power is 2.0 W. During surgery, the laser beam is turned on for 0.057 s. During this time, how many photons are emitted by the laser

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
