A double slit apparatus is held 1.2 m from a screen. [___/4] (a) When red light (λ = 600 nm) is sent through the double slit, the interference pattern on the screen shows a distance of 12.5 cm between the first and tenth dark fringes. What is the separation of the slits? (b) What will be the difference in path length for the waves travelling from each slit to the tenth nodal line?

Answers

Answer 1

A. To solve for part A, we use the formula of Young’s double slit equation:

x = λ L m / d

Where,

x = distance between adjacent dark lines or fringes = 12.5 cm = 0.125 m

λ = wavelength of light = 600 × 10^-9 m

L = distance from the two sources of light to the screen = 1.2 m

m = number of fringes = 10 (tenth) – 1 (first) = 9

d = separation of slits = unknown

 

Rearranging the equation in terms of d and plugging in the values:

d = λ L m / x

d = (600 × 10^-9 m) (1.2 m) (9) / 0.125 m

d = 5.184 × 10^-5 m

d = 51.84 μm

 

B. The formula for path difference is:

path difference = (2 m + 1) (λ / 2)
path difference = (2 * 9 + 1) (600 × 10^-9 m / 2)

path difference = 5.7 × 10-6 m
path difference = 5.7 μm

Which trait shared by dolphins and bats possibly lead to the evolution of echolocation in these two animal groups?

Answers

The need to quickly move through dark environments.  

Answer:

the need to move quickly through dark environments

Explanation:

Dolphins and Bats are those  creature who uses echolocation in the path which is one property which give them edge in night because they can easily locate things which any other creature face difficult to locate.  

In echolocation what bat and dolphins do is the emit ultra sonic waves which gets deflected from the object and from the deflection they get to know the position of the objects.  

Why is it important for scientist to use the international system of units

Answers

In my opinion it's like a one language, for example when you are trying to work with collaboration, and let's assume that the people around you are speaking in different language, it makes no sense if you all start to figure out what's going on because you can't understand each other... But if everyone speaks in one language, everything will work like a charm.

In this case scientist uses international system of units because, if he/she needs some help from others, he/she can easily ask others because everyone can understand those units that he/she is using....

I hope it makes sense.

The Brain Adventure

Once upon a time in Brain City, there were three special friends: Smarty the Cerebrum, Memory the Hippocampus, and Swift the Brainstem. Smarty helps us think and learn, Memory stores our favorite stories and experiences, while Swift keeps our heart beating and helps us run fast when we play soccer.

Our brain is like a superhero team, with each part playing a different role to keep us healthy and happy. So, next time you kick a soccer ball or learn a new dance move, remember to thank your brain friends for making it all possible!
