The answer is 4.
The speed of light is faster in the air than in the glass, because a wavelength can be refracted in glass. Because the speed increases when the light wave passes from glass into air, the wavelength will also increase.
Answer:
Slit separation, 
Explanation:
It is given that,
Wavelength of light, 
The angle between the central bright fringe and the second dark fringe, 
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is 
. Hence, this is the required solution.
This is true.
Hope this helps
We can use the equation of
E = mc△T
To calculate the total heat absorbed.
E is the total heat absorbed (energy used)
m is mass.
c is specific heat capacity and
△T is the temperature change.
E = 125 x 4.184 x (32.8 - 25.2)
E = 3974.8 J
Therofre the total heat absorbed is 3974.8 joules.
