In a two-slit experiment, the slit separation is 3.00 × 10-5 m. The interference pattern is created on a screen that is 2.00 m a

balu736 [363]

Answer:

The value is $\lambda = 214.3 \ nm$

Explanation:

From the question we are told that

The slit separation is $d = 3.00 * 10^{-5} m$

The distance of the screen is $D = 2.00\ m$

The order of fringe is n = 7

The path difference is $y = 10.0 \ cm = 0.1 \ m$

Generally the path difference is mathematically represented as

$y = \frac{n * \lambda * D}{ d}$

=> $0.1 = \frac{7 * \lambda * 2.00 }{ 3.00 * 10^{-5}}$

=> $\lambda = \frac{0.1 *3.00 * 10^{-5} }{7 * 2.00 }$

=> $\lambda = 2.143 *10^{-7} \ m$

=> $\lambda = 214.3 \ nm$

Do the math for 30%÷75

Dafna1 [17]

" 30% " means " 0.30 "

30% ÷ 75 means (0.30 / 75) = <em>0.004</em>

How do u convert 7.68 cal/sec to kcal/min

stich3 [128]

<span>First you have to convert 7.68 cal/sec to cal/min to do that, just multiply by 60 So it will be 460.8 cal/min now convert that to kcal/min kcal = kilocalories = 1000 calories. so just divide by 1000 and youll have your answer in kcal/min </span>
