A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from central maximum, when monochromatic

light of 630-nm wavelength is used. The same slit, illuminated by a new monochromatic light source, produces a diffraction pattern with the second minimum at a 60.0° angle from the central maximum. What is the wavelength of this new light?

Answer:

\lambda = 424.4 nm

Explanation:

As we know by the formula of diffraction

a sin\theta = N\lambda

so we have

a = slit size

\theta = angular position of Nth minimum

so we will have

for first minimum of 630 nm light

a sin40 = 1(630 \times 10^{-9})

a = 9.8 \times 10^{-7} m

Now for another wavelength second minimum is at 60 degree angle

a sin60 = 2 \lambda

(9.8 \times 10^{-7}) sin60 = 2 \lambda

\lambda = 424.4 nm

Answer:

Explanation:

1) for a given n value the l value can be from 0 to n-1

So if n= 5 it can take 0,1,2,3,4

i.e it can take 5 values

2)for an electron with l =3

it can be from -3 -2 -1 0 1 2 3

i.e it can take 7 values

3) n = 3 !!

l = 0 , 1 , 2

for l=0 , m = 0 total = 1

for l= 1 ,m = -1,0,1 total = 3

for l = 2, m=-2,-1,0,1,2 total = 5

5+3+1 = 9

total possible states = 9 * 2 = 18

Answer is 168

4)given l=3 and n=3

orbital quantum number cannot be equal to principal quantum number

its max value is l-1 only

5)L = sqrt(l(l+1))x h'

for it to be max l should be max

for n = 3 max l value is 2

therfore it is sqrt(2(2+1)) x h'

\sqrt(6) \times h'

this is the answer

Define neuron and nerve<br>cell​
san4es73 [151]

Answer: Hi!

A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.

Hope this helps!

Explain briefly why metals are good conductors of electric current
Mice21 [21]
The free electrons in metals can move through the metal, all while receiving and losing electrons, allowing metals to conduct electricity. Example: copper is a great conductor of electric current.
