How are the types of energy in the electromagnetic spectrum defined? (Points : 3)by their atomic structure

by their color

by their amplitude

by their wavelength

Answers

Answer 1
Answer:

The energy associated with the electromagnetic spectrum is given by the wavelength of the spectrum.

Further Explanation:

The electromagnetic waves are the waves which travel through the space and do not require any medium for their propagation. The Electromagnetic waves are the waves which are transverse in nature.

There are several waves of various wavelength and frequency present in the Electromagnetic spectrum. The different waves present in the electromagnetic spectrum are:

  • Gamma rays.
  • X-rays.
  • Ultraviolet rays.
  • Visible rays.
  • Infrared rays.
  • Micro waves.
  • Radio waves.

The wavelength and the frequency of the electromagnetic waves are the key properties of the wave which describe several other parameters of the waves like intensity, power, energy of the wave etc.

The energy associated with the electromagnetic radiation is given by:

 E=\frac{{hc}}{\lambda}

Here, E  is the energy of the radiation, h  is the plank’s constant, c  is the speed of the light and \lambda  is the wavelength of the radiation.

Therefore, the above expression shows that the energy of the electromagnetic spectrum depends on the wavelength of the spectrum.

Thus, Option (d) is correct. The energy of the electromagnetic spectrum is defined by their wavelength.

Answer 2
Answer:

The correct answer to the question is : C) By their wavelength

EXPLANATION:

Before going to answer this question, first we have to understand the electromagnetic spectrum.

An electromagnetic wave is the transverse wave which contains time varying electric field and magnetic field which are perpendicular to each other as well as perpendicular to the direction of propagation.

There are various electromagnetic waves which are named as gamma ray, X-ray, U.V ray, visible light, infrared wave, micro wave and radio waves respectively. Out of these waves, only visible light can be visualized by human eye.

Every electromagnetic wave is characterized by its wavelength. Different waves have different range of wavelength.

The electromagnetic spectrum is the the arrangement of electromagnetic waves either in ascending order of wavelength or in descending order.

The gamma ray has the minimum wavelength in the spectrum, and radio wave has the maximum wavelength.

The energy carried by electromagnetic waves having wavelength \lambda is calculated as-

                  Energy = (hc)/(\lambda)

Here, c is the velocity of light and h is the Planck' s constant.

Hence, the correct answer to the question is wavelength which will signify the energy of different types of electromagnetic waves.

When a baseball player catches a baseball, the glove "gives" or moves backward. How does this movement affect the change in momentum of the baseball? The change in momentum increases because the impact time increases. The change in momentum decreases because the force decreases. The change in momentum stays the same because the ball still comes to a stop. The change in momentum depends on the initial speed of the ball and the time to stop.

Answers

Answer:

v = 350 m/s

Explanation:

The speed of sound depends on the temperature of surrounding. The relation between the speed of sound and the temperature is given by :

v=331+0.61T

Where, T is temperature in Celsius

Here, T = 30 degree Celsius

v=331+0.61* 30

v = 349.3 m/s

or

v = 350 m/s

Therefore, the speed of sound in air at 30 degrees Celsius is 350 m/s.

Answer:

the answer is 350 m/s

Can you put hot water in a insulated gatorade cooler

Answers

You can put hot water in a insulated Gatorade cooler. This is correct.

What is insulation?

Insulation is the phenomenon in which the heat is blocked to flow out of the control volume.

Given is aGatorade cooler that is insulated. The insulation will not let any heat to pass to the cooler.

But pouring hot water may damage the plastic body of the cooler.

So, the cooler efficiency will have no effect.

Thus, yes, we can put hot water on insulated Gatorade cooler.
