The rhinestones in costume jewelry are glass with index of refraction 1.50. To make them more reflective, they are often coated

anyanavicka [17]

Answer:

$T=62.9*10^{-9}$

Explanation:

From the question we are told that:

Index of refraction of Rinestones $\gamma_1 =1.5$

Index of refraction of silicon $\gamma_2 =2.0$

Wavelength $\lambda=576nm=576*10^{-9}$

Let each layer have thickness T

Therefore

Total Thickness =2T

Generally the equation for Constructive interference is mathematically given by

$2T=(m+0.5)\frac{l\lambda}{\gamma_2}$

Where

$M=0$

$2T=(0+0.5)\frac{576*10^{-9}}{2*2.0}$

$T=62.9*10^{-9}$

A wave with a wavelength of 125 meters is moving at a speed of 20 m/s. What is it’s frequency

IceJOKER [234]

Answer:

0.16Hz

Explanation:

wavelength (λ) = 125 meters

speed (V) = 20 m/s

frequency (F) = ?

Recall that frequency is the number of cycles the wave complete in one

second. And its value depends on the wavelength and speed of the wave.

So, apply the formula V = F λ

Make F the subject formula

F = V / λ

F = 20 m/s / 125 meters

F = 0.16 Hz
