In a double-slit interference experiment, the distance y of the maximum of order m from the center of the observed interference pattern on the screen is
where D=5.00 m is the distance of the screen from the slits, and
is the distance between the two slits.
The fringes on the screen are 6.5 cm=0.065 m apart from each other, this means that the first maximum (m=1) is located at y=0.065 m from the center of the pattern.
Therefore, from the previous formula we can find the wavelength of the light:
And from the relationship between frequency and wavelength,
, we can find the frequency of the light:
The metallic elements which all react to water are found in the same group, the groups name is the Alkali metals, or also known as group one.
Explanation:
Given that,
The box of oranges cannot exceed a mass of 10.222 Kg if we are sending to a friend by mail.
The mass of each orange is 198 g
We know that,
1 kg = 1000 g
10.222 kg = 10.222×1000 g
Let there are n number of oranges. So,
It means she can send 52 oranges and it is maximum quantity.
Answer:
The temperature and volume of a gas are directly proportional when pressure is constant.
Explanation:
Charles's Law was proposed by a French chemist, Jacques Charles. The law states that "The volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
The law shows the relationship between volume and temperature at a constant temperature. It is mathematically expressed as:
V∝T(P,n constant)
As the distance between two magnets increases, the force between them <em>decreases</em>.
If the force increased along with distance, then the magnet in your hand would reach out
and grab every magnet in Australia or on Mars and pull it toward you.
