The part of the atom that accounts for electricity is the electron. The correct option among all the options given in the question is option "D". Electrons are capable of moving from one atom to another very easily. The flow of the electrons is actually responsible for electricity to pass. When one electron starts moving in one direction, the other starts following it and this results in the flow of electricity.
Answer:
The wavelength of radio waves is much longer than the wavelength of visible light waves
Explanation:
Electromagnetic waves are periodic oscillations of the electric and the magnetic fields, occuring in a plane perpendicular to the direction of motion the wave.
Electromagnetic waves are the only waves able to travel in a vacuum; they travel at the speed of light:
Electromagnetic waves are also classified into 7 different types, according to their wavelength/frequency. From longest to shortest wavelength, we have: (with the corresponding wavelength written in the brackets):
Radio waves (>1 m)
Microwaves (1 mm - 1 m)
Infrared (750 nm - 1 mm)
Visible light (380 nm - 750 nm)
Ultraviolet (10 nm - 380 nm)
X-rays (0.01 nm - 10 nm)
Gamma rays (<0.01 nm)
So from the table, we can see that:
The wavelength of radio waves is much longer than the wavelength of visible light waves.
E the temperature of a substance. Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand , on the other hand, have lower specific heats. This means that their temperatures change more quickly. When the summer sun shines down on them, they quickly become hot.
