Uhh it is used to detirmine heat
Answer:
The longest wavelength of light is 666.7 nm
Explanation:
The general form of the grating equation is
mλ = d(sinθi + sinθr)
where;
m is third-order maximum = 3
λ is the wavelength,
d is the slit spacing (m/slit)
θi is the incident angle
θr is the diffracted angle
Note: at longest wavelength, sinθi + sinθr = 1
λ = d/m
d = 1/500 slits/mm
λ = 1 mm/(500 *3) = 1mm/1500 = 666.7 X 10⁻⁶ mm = 666.7 nm
Therefore, the longest wavelength of light is 666.7 nm
Answer:
10.32874 m
Explanation:
= Atmospheric pressure = 101325 Pa
g = Acceleration due to gravity = 9.81 m/s²
h = Height of water
= Density of water = 1000 kg/m³
If the walls of the tube do not collapse that means that maximum pressure inside will be the atmospheric pressure
Atmospheric pressure is given by
The maximum height to which Superman can lift the water is 10.32874 m
On the Moon there is no atmosphere so no atmospheric pressure which means when the straw is placed in water water will not rise in the tube.
Answer:
The distance between the two successive crests of the wave is 360m
Explanation:
Wavelength is defined as the property of wave in which the distance between identical points between two successive waves are calculated
Wavelength is referred to as the <em>distance between two successive crests or troughs</em>
<em>Given that:</em>
speed = 72.0 m/s
time = 5 seconds
Using the formula
C = fλ
Where C = speed, f = freequency and λ = wavelength
F = 1 / time
F = 1/5
F = 0.2Hz
From the fomula C = fλ
make λ the subject of the formula
λ = C / f
λ = 72/0.2
<em>λ = 360m</em>
