Refraction is simply the bending of light when it moves from one material into another. If light is beamed at 90° to a surface, no bending happens. But if you shine the light at an angle it will bend one way or another.
Diffraction is a process in which a beam of light travels through a gap or around a barrier, and spreads out as a result.
<span> Dispersion is the property that the speed of light in a transparent material is different for different wavelengths. Thus the index of refraction is likewise different.</span>
Answer:
d= 0.242 mm
Explanation:
Slit width (d ) = ?
Screen distance ( D ) = 1.25 m
Wave length of light λ = 600 nm
Distance of n the dark fringe from centre
= n λ D / d
Here n = 2
so
d= 0.242 mm
Q = heat energy , m=mass , c=specific heat , delta T= change in temperature
as you know heat is a form of energy which is <em>usually</em> measured in Joules according to the SI. and also we usually use kilograms for mass.
so you need to know the mass, specific heat, and change in temperature in order to find out the heat energy :)
Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).
