Solar cells are often coated with a transparent, thin film of silicon monoxide (n = 1.45) to minimize reflective losses from the

Alinara [238K]

Answer:

94.82 nm

Explanation:

We have given that wavelength $\lambda=550\ nm$

We have to find the minimum film thickness that produces the least reflection

minimum thickness is given by $t=\frac{\lambda }{4n}$

here n is given n=1.45

so minimum thickness $t=\frac{550 }{4\times 1.45}=94.82\ nm$

so the minimum film thickness will be 94.82 nm

Explanation:

Here is the complete question

Ricardo is on vacation, doing some mountain climbing. He notices that the higher he goes up a mountain, the colder he feels. He remembers his physics teacher teaching about these types of relationships. What is the type of relationship between mountain elevation and temperature? A. a positive relationship B. an inverse relationship C. a neutral relationship D. a direct relationship

Solution

It is an inverse relationship because, as Ricardo's mountain elevation increases, he feels colder. So, as his mountain elevation increases, the temperature decreases.

Since one variable decreases while the other increases, it can only be an inverse relationship.

Let h be Ricardo's mountain elevation and T his temperature. So by inverse proportionality,

h ∝ 1/T

h = k/T

hT = k = constant

So, we have an inverse relationship and B is the answer.
