11. Highlight your In a double slit experiment with slits 1.00x10^-5m apart, light casts the first bright
band 3.00x10^-2m from the central bright spot. If the screen is 0.650 m away, what is the wavelength of
this light?

λ  ≈ 462 nm  

Explanation:

Given:-

- The slit separation, a = 10^-5 m

- The first bright fringe occurs at, y = 0.03 m from central order

- The distance between the screen and slit, L = 0.65 m

Find:-

what is the wavelength of  this light?

Solution:-

- The Young's double slit experiment gives us the relation for the interaction of a light with wavelength ( λ ) that pass through 2-slits with separation ( a ) and interfere constructively or destructively at the the screen Hence, forming an interference pattern of bright and dark fringes.

- The relation for separation ( y ) between bright fringes is related to the above mentioned parameters as given below:

                      y = L*n*λ / a

Where,

                 n: The order of fringe from central

Re-arrange for wavelength ( λ ).

- The order of first bright fringe is n = 1:

                      λ  = y*a / L

                      λ  = 0.03*0.00001 / 0.65

                      λ  = 4.61538 * 10^-7 m

                      λ  ≈ 462 nm  

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
