What is the first wave in the electromagnetic spectrum?

1 answer:

4 0

All radio waves (such as commercial radio and television, microwaves, and radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays are all included in the entire electromagnetic spectrum, which ranges in frequency from the lowest to the highest (longest to shortest wavelength).

<h3>What caused electromagnetic waves to begin?</h3>

James Clerk Maxwell was the first to propose the existence of electromagnetic waves, and Heinrich Hertz was the second. An electric and magnetic field vibrating together results in electromagnetic waves.

<h3>What are the seven different kinds of electromagnetic waves used for?</h3>

EM waves are all instances of the same phenomena, not withstanding the sciences' broad classification of them into seven fundamental categories.

Instant communication through radio waves.
Microwaves: Information and Heat.
invisible heat radiated by infrared waves.
Rays of Visible Light.
Energetic Light: Ultraviolet Waves
Penetrating Radiation: X-Rays.
Nuclear energy: gamma rays.

<h3>Why is the electromagnetic spectrum called that?</h3>

The term for the collection of all electromagnetic radiation in the cosmos is the electromagnetic spectrum, or EM spectrum. In the form of electric and magnetic waves, this kind of energy permeates the cosmos and enables the transmission of information and energy.

Suppose you are on a cart, initially at rest, which rides on a frictionless horizontal track. You throw a ball at a vertical sur

Len [333]

Answer:

$F_c t_ c = -F_b t_b$

And the forces are equal but in the opposite direction. So then we can write by general rule:

$m_c \Delta V_{c} = -m_b \Delta V_b$

Or equivalently:

$m_c \Delta V_{c} +m_b \Delta V_b =0$

Where: $V_c$ represent the speed of the car and $V_b$ the speed of the ball

$m_c$ represent the mass of the car

$m_b$ represent the mass of the ball

Since the ball is moving to the left and we assume that the total momentum not changes then the car need to move to the right in order to satisfy the equation and satisfy the balance.

By conservation of the momentum the car will move to the right since the ball is moves to the left.

So then the correct option for this case is :

A.Yes, and it moves to the right.

Explanation:

If we assume that we have the situation in the figure attached.

For this case we assume that the momentum changes are equal in magnitude and opposite in direction, so then we satisfy this:

$F_c t_ c = -F_b t_b$

And the forces are equal but in the opposite direction. So then we can write by general rule:

$m_c \Delta V_{c} = -m_b \Delta V_b$

Or equivalently:

$m_c \Delta V_{c} +m_b \Delta V_b =0$

Where: $V_c$ represent the speed of the car and $V_b$ the speed of the ball

$m_c$ represent the mass of the car

$m_b$ represent the mass of the ball

Since the ball is moving to the left and we assume that the total momentum not changes then the car need to move to the right in order to satisfy the equation and satisfy the balance.

By conservation of the momentum the car will move to the right since the ball is moves to the left.

So then the correct option for this case is :

A.Yes, and it moves to the right.

KIM [24]

Answer:

9.6m/s

Explanation:

Using the equation S=d/t where s=speed, d=distance, and t=time

plug in the known variables

S=120m/12.5s

S=9.6m/s
