Complete Question
In a double-slit arrangement the slits are separated by a distance equal to 150 times the wavelength of the light passing through the slits. (a) What is the angular separation between the central maximum and an adjacent maximum? (b) What is the distance between these maxima on a screen 57.9 cm from the slits?
Answer:
a
b
Explanation:
From the question we are told that
The slit separation is
The distance from the screen is
Generally the condition for constructive interference is mathematically represented as
=>
where n is the order of the maxima and value is 1 because we are considering the central maximum and an adjacent maximum
and is the wavelength of the light
So
Generally the distance between the maxima is mathematically represented as
=>
=>
Answer:
<em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N </u></em><em><u>and </u></em><em><u>F2 </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
Explanation:
<em>Formula </em><em>used </em><em>=</em><em>></em><em> </em><em> </em><em>F </em><em>=</em><em> </em><em>m×</em><em>a</em><em> </em><em>and </em><em>v-u=</em><em> </em><em>at</em>
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
<em>FOR </em><em>1</em><em>S</em><em>T</em><em> </em><em>BLOCK</em>
16= <math> F1/5 </math> × 5 ==> <em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N</u></em>
<em>FOR </em><em>2</em><em>N</em><em>D</em><em> </em><em>BLOCK</em>
15= <math> F2/ 8 </math> × 5 ==> <em><u>F2=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
Answer: 760 N
Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.
When Lucy stands on the weighing scale, net force due to gravity is
Hence, weight of Lucy is 760 N
Given what we know, we can confirm that if the wavelength of light were increased, its frequency and therefore energy would decrease.
<h3>Why do frequency and energy decrease?</h3>
The frequency of light waves is measured through the wavelengths. Shorter waves result in higher frequencies, and since these waves are increasing in length, the frequency will decrease. Since the frequency decreases, the waves lose kinetic energy, and thus the energy decreases.
Therefore, we can confirm that if the wavelength of light were increased, its frequency and therefore energy would decrease.
