From young's experiment, how does the frequency of light affect the number of lines observed?

a. higher frequencies equal more lines

b. lower frequencies equal more lines

c. higher frequencies have larger spaces between lines

d. lower frequencies have smaller spaces between lines

Answer : (C) "Higher frequencies have larger spaces between lines".

Explanation:

In Young's experiment, the condition for constructive interference is given by :

.........(1)

n is order or number of lines observed

d is distance between slits

is the angle between the path and the line from screen to the slits.

We also know that,

or

where,

c is the speed of light

is frequency

is wavelength

So, equation (1) turns into

So,

or

Higher frequencies have larger spaces between line.

So, correct option is (C).

A: Higher frequencies equal more lines

Explanation:

I took the test and that's the answer. (See screen shot below)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
