Light with a wavelength of 587.5 nm illuminates a single slit 0.750 mm in width.
(a.) at what distance from the slit should a screen be located if the first minimum in the diffraction pattern is to be 0.850 mm from the center of the screen?
b.) what is the width of the central maximum?
(c.) sketch the intensity distribution for the diffraction pattern observed on the viewing screen.
the correct answer would be b. the first law.
the first law of thermodynamics is also known as the law of conservation of energy, and establishes that energy cannot be created or destroyed, and is only seen to be transformed from one form to another, in an isolated system.
for example, it may seem like pressing a button may generate light energy from a bulb, but it is actually the conversion of electrical energy into light energy.
similarly, in a circuit run from battery, chemical energy (of the battery) is converted into light energy. this energy is seen to be converted into the form of heat energy which is emitted from the bulb.
hope this !
here, i hope this .
to answer this problem, let's call:
p: monthly budget
consumption of household appliances.
consumption of kitchen appliances.
we know that:
then, if :
