They will feel equally hot or cold at the same temperature.
What do you mean by temperature?
Temperature is a physical parameter that describes how hot stuff or radiation is. There are 3 different types of temperature scales: those described in regards to the average translational kinetic energy per freely moving microscopic substance in a body, such as a atom, compound, or anion, such as the SI scale; those that rely solely on purely <u>macroscopic properties and thermodynamic principles</u>, such as Kelvin's original definition; <u>and those that are not defined by theoretical principles, but are defined by convenient empirical properties of particulate matter.</u>
If they are the same temperature as the area of your body that is touching them, they will feel equally hot or cold. There will be no heat movement if the wood and iron at the same temperature as the skin, and the iron's higher thermal conductivity will be irrelevant. <u>The </u><u>specific temperature</u><u> cannot be specified because if you touch the materials with your fingertips, the wood and iron must match that</u><u> temperature</u><u>, and if you test them with your tongue, which is often considerably </u><u>warmer </u><u>than your hands, the wood and iron must be </u><u>warmer</u><u>.</u>

Green has a shorter wavelength.
It is very easy..let me tell you.. there are seven colors in the rainbow. Isn't it?
According to their decreasing order of wavelength , they are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet.
It is as simple as that to remember....
Answer:
Amplitude, A = 5 m
Explanation:
Let a progressive wave is given by equation :
.....(1)
The general equation of a progressive wave is given by :
....(2)
Here,
A is the amplitude of the wave
is the angular frequency
k is propagation constant
We need to find the amplitude of the wave.
If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
