What is the minimum thickness of a nonreflecting film coating (n = 1.30) on a glass lens (n = 1.50) for wavelength 500 nm?
Burka [1]

The thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.

From the question we know that :

n = 1.30

λ = 500nm = 5 x 10¯⁷m

The non-reflective coating system is applied on glass and the refractive index of that system should be  <em>nair</em> < <em>ncoating</em> < <em>nglass. </em>The light travels across the air and is refracted by coating film and then refracted again by the glass. For preventing the light got reflected by glass, the thickness of the layer should obey this equation :

2nt = λ/2

t is the thickness of the layer, λ is the wavelength and n is the refractive index of the film.

By substituting the following equation we get

2nt = λ/2

t = 1/4 . ( λ / n )

t = 1/4 . ( 5 x 10¯⁷ / 1.3)

t = 9.62 x 10¯⁸ m

Hence, the thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.

timama [110]

Answer:

since 4 is 132,then 8 is also 132( corresponding angle)

so,8+7=180( adjacent angle)

so,132+7=180

7=180-132

7=48

Mary is paid $12 per hour at her weekend part-time job. She earns an average of $132 each weekend, but her earnings can vary by
RSB [31]

Given:

Mary is paid $12 per hour at her weekend part-time job.

She earns an average of $132 each weekend, but her earnings can vary by $36.

To find:

The inequality for number of hours.

Solution:

Let h be the number of hours Mary could work in one weekend.

Total earning for h hours = $12h

She earns an average of $132 each weekend, but her earnings can vary by $36. So,

132-36\leq \text{Total earning}\leq 132+36

96\leq \text{Total earning}\leq 168

96\leq 12h\leq 168

Divide all sides by 12.

\dfrac{96}{12}\leq \dfrac{12h}{12}\leq \dfrac{168}{12}

8\leq h\leq 14

Therefore, the correct option is D.
