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)
How many stars are in Pegasus and Cassiopeia together?
Answer:26
Explanation:
Which trait shared by dolphins and bats possibly lead to the evolution of echolocation in these two animal groups?
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
You are to create a story for a child of 5-6 years old. You will explain the brain and its functions to them. You need to use the following terms and explain their functions in simple terms. Use the format of a story to keep the child interested, and be sure to use illustrations. Add characters (Dora, Superman, etc.) to make the information fun.
This response uses a fun story to explain the functions of different parts of the brain to children, emphasizing their roles in daily activities.
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!
