Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.
The ruling separation is d=1/(470mm-1)
Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.
Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.
we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.
That is,find the greater integer value of m for which mλ<d.
since,d/λ
There are three complete orders on each side of the m=0 order.
The second and third orders overlap.

Answer:
D
Explanation:
The north field of a magnet is the positive side. Arrows pointing out of a side = positive
Answer:
heat energy
Explanation:
heat is the flow of thermal energy. A whole branch of physics
Answer:
The answer to your question is letter D.
Explanation:
In physics, mechanical work is the energy transferred by a force and its formula is Work = Force x distance.
Data given
Force = 90 N
Distance = 50 m
Work = ?
Substitution
Work = 90 N x 50 m
Simplification and result
Work = 4500 Nm = 4500 J
Answer:
Heat is transferred directly from one particle of matter to another by the process of conduction.
A circular flow of warmer fluid and cooler fluid is called convection
Heat is always transferred from conduction to radiation
radiation is the transfer of energy by electromagnetic waves.
Heat that is transferred by the movement of currents within a fluid is called conduction
The only form of heat transfer that does not require matter is specific heat
Water bubbles up through a hot spring at Yellowstone National Park. What method of heat transfer is this?
convection
