<span>1. </span>Electromagnetic
radiation are represented in waves. Each type of wave has a certain shape and
length. The distance between two peaks in a wave is called the wavelength. This
value is equal to the speed of light divided by the frequency.

Wavelength = 150 m
Answer:

Explanation:
We know that the volume of the material
= mass/density
mass= 360 Kg
density = 1450 kg/m^3
Volume= 360/1450= 0.248 m^3
and Volume = Area× equivalent Diameter
Area= 1200 m^2
⇒Equivalent Diameter= Volume/Area= 0.248/1200=
