For Fraunhofer diffraction at a single slit would be represented by:
<span>a sinθ = mλ
</span><span>It should be noted that the angle needs be halved because we are only concerned with the angle between m=1 and m=0 and they gave you the angle between m=1 to the right of the center and m=1 on the left of the center. We calculate as follows:
</span>
<span>a sin(45/2)=(1)(470)
a = 1228 nm
Hope this answers the question. Have a nice day.

Answer:
Variable- not consistent or having a fixed pattern; liable to change
Data- facts and statistics collected together for reference or analysis
Control- a group or individual used as a standard of comparison for checking the results of a survey or experiment
Technology- the application of scientific knowledge for practical purposes, especially in industry
Hypothesis- a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation
Physical Science- the sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects
Experiments- a scientific procedure to make a discovery, test a hypothesis, or demonstrate a known fact
Explanation:
Answer:
The flow of energy from falling water to the steam is;
a) Mechanical → Mechanical → Electrical → Thermal → Thermal
Explanation:
1) Mechanical → Mechanical
The water in the pipe before it falls possesses potential energy which it converts into kinetic energy as it falls from height
2) Mechanical → Mechanical
The water falling from the pipe stream unto the turbine wheel transfers its kinetic (mechanical) energy due to its motion on to the turbine wheel to give the wheel rotational motion
3) Mechanical → Electrical
The kinetic (mechanical) energy from the rotating turbine wheel is converted into electrical energy in the electrical generator which transported through the electrical circuit
4) Electrical → Thermal
The electrical energy from the electric current is then converted into thermal energy as the current passes through the resistors in the heating filament
5) Thermal → Thermal
The heated filament transfers thermal energy to the the water in the beaker by conduction which raises the temperature of the water such that as the water acquires more thermal energy it turns into steam
Therefore, we have the flow of energy from the falling water to steam as follows;
1) Mechanical 2) Mechanical 3) Electrical 4) Thermal 5) Thermal
Answer:
Any object that is being acted upon only by the force of gravity is said to be in a state of free fall.
