In your spare-time job as an assistant museum curator, you are thinking about glare (light reflection) off the glass covering the artwork. You want to apply a thin coating to reduce the glare by destructive interference between the light reflected from the coating, and the light from the glass. Assume the glass has an index of refraction of n=1.62 and the coating is titanium dioxide (TiO2) with n=2.62. a) What are the three smallest thicknesses of coating you could use for light of λ=460 nm (fluorescent lights)? Assume perpendicular incidence. b) If your boss decides to change the lighting to a reddish colour (λ=575 nm), which of the above values of thickness will still provide the anti-glare coating you want?

terd muffin is the correct answer

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!

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
