An oil film with index of refraction 1.64 is trapped between two pieces of glass with index of refraction 1.43. no light is reflected by such a film when 578 nm light falls on it at normal incidence. what is the nonzero minimum thickness of the oil film that will satisfy these conditions? answer in units of nm.

176.22 nm

Explanation:

= Index of refraction of oil = 1.64

= Wavelength of the light = 578 nm

= minimum thickness of the oil

For destructive interference, we have

For minimum thickness, m = 1

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!

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
