Answer:
Option (4)
Explanation:
The radiation are defined as the energy that is liberated from atoms in the form of electromagnetic waves or minute particles of matter. For example, the radiations that are emitted from the sun in the form of light.
This radiations are mainly of 3 types. This includes-
(a) Alpha Radiation- These are the short ranged particles and are very heavy. This radiations cannot penetrate the human skins but they can cause harmful diseases.
(b) Beta Radiation- These are also the short-ranged particles but they lighter. This radiations can penetrate the human skin upto the depth where the new skins are created.
(c) Gamma Radiation- These are highly dangerous and are penetrable to the human skin. This type of radiations are often used for the medical purposes.
Thus, the correct answer is option (4).
[Density]
Density determines waters vertical position in the ocean using temperature and salinity. Lower temperature waters are more denser than higher temperature waters. Also, low salinity waters are lower density than higher salinity waters

Answer:
So the wavelength of light is 1015.7 nm
Explanation:
From Wein's displacement law, we can write the following formula;
here, 
is the wavelength of maximum radiation in meters
T is the absolute temperature (in Kelvin) for maximum radiation
K is the constant has a value of 
Given here, T = 2853 K
And we need to find
Putting the values in formula
