Explanation:
what is the temperature of a wave that has a wavelength of 5 m?
So, the temperature of a wave that has a wavelength of 5 m is [tex] \boxed{\sf{5.796 \times 10^{-4} \: K}} [/tex]
IntroductionHi ! Here, I will help you to explain about The relationship between temperature and electromagnetic wavelength uses the principle of Wien's Constant. According to Wien, if we multiply temperature with the electromagnetic wavelengths will always got the same number (constant). Therefore, The relationship is expressed in this equation :
[tex] \boxed{\sf{\bold{C = \lambda_{max} \times T}}} [/tex]
With the following condition :
C = Wien's constant ≈ [tex] \sf{2.898 \times 10^{-3} \: m.K} [/tex][tex] \sf{\lambda_{max}} [/tex] = wave at its longest point (m) T = absolute temperature (K)Problem SolvingWe know that :
C = Wien's constant ≈ [tex] \sf{2.898 \times 10^{-3} \: m.K} [/tex][tex] \sf{\lambda_{max}} [/tex] = wave at its longest point = 5 mWhat was asked :
T = absolute temperature = ... KStep by step :
[tex] \sf{C = \lambda_{max} \times T} [/tex]
[tex] \sf{2.898 \times 10^{-3} = 5 \times T} [/tex]
[tex] \sf{T = \frac{2.898 \times 10^{-3}}{5}} [/tex]
[tex] \sf{T = \frac{2.898 \times 10^{-3}}{5}} [/tex]
[tex] \sf{T = 0.5796 \times 10^{-3}} [/tex]
[tex] \boxed{\sf{T = 5.796 \times 10^{-4} \: K}} [/tex]
Conclusion :So, the temperature of a wave that has a wavelength of 5 m is [tex] \boxed{\sf{5.796 \times 10^{-4} \: K}} [/tex]

What do you think causes such change in wave velocity?
Example: Increasing the tension in A string causes the speed of waves on the string to increase. Since the wavelengths of the standing waves remains constant, this results in a larger frequency of oscillations in the string, which we percieve as a higher pitch when the string vibrates the air.

The diameter of earth is largest when measured around the.
Answer:
equator
Explanation:
The diameter of earth is largest when measured around the equator, due to the equatorial bulge.
The equatorial bulge is a phenomenon caused by the Earth's diameter being wider in the Equator.
A straight line with its endpoints located on the edge of the circle and its center is used to calculate the diameter of a circle. Latitudes like the equator and the Arctic Circle have diameters that can be calculated by scientists.
The Equator is the place on Earth where it is the broadest. At the equator, the circumference of the Earth is 40,075 km.

The potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.
What is Potential energy of a body?The energy of the body due to its position is called potential energy. If a body of mass 'm' is at height 'h' above the ground, then its potential energy with respect to earth will be -
E[P] = mgh
Given is a fighter jet traveling at a height of 10,000 meters.
The potential energy of a body at height 'h' above the ground is given by-
E[P] = mgh
where -
m is the mass of body
g is the acceleration due to gravity
Assume that the mass of jet fighter is 'm'. Then its potential energy will be -
E = mgh
E = m x 9.8 x 10000
E = 98000m
Therefore, the potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.
