<span>A continuous spectrum is one where the light emitted goes along the entire spectrum. A line spectrum is one that only emits a few frequencies. </span>
I'm going to say a Human.
In one simple statement, Humans have survived all of earth's devastation because of evolution. At one point it is believed that the earth had changing conditions including that some of the food that we hunted in waters became extinct. Then, as lack of food grew, We gained the ability to walk on land. As this happened, we began to adapt to our surroundings, including gaining the ability to walk on two legs and use tools
Answer:
If the particle is an electron ![E_y = 3.311 * 10^3 N/C](https://tex.z-dn.net/?f=E_y%20%3D%203.311%20%2A%2010%5E3%20N%2FC)
If the particle is a proton, ![E_y = 6.08 * 10^6 N/C](https://tex.z-dn.net/?f=E_y%20%3D%206.08%20%2A%2010%5E6%20N%2FC)
Explanation:
Initial speed at the origin, ![u = 3 * 10^6 m/s](https://tex.z-dn.net/?f=u%20%3D%203%20%2A%2010%5E6%20m%2Fs)
to +ve x-axis
The particle crosses the x-axis at , x = 1.5 cm = 0.015 m
The particle can either be an electron or a proton:
Mass of an electron, ![m_e = 9.1 * 10^{-31} kg](https://tex.z-dn.net/?f=m_e%20%3D%209.1%20%2A%2010%5E%7B-31%7D%20kg)
Mass of a proton, ![m_p = 1.67 * 10^{-27} kg](https://tex.z-dn.net/?f=m_p%20%3D%201.67%20%2A%2010%5E%7B-27%7D%20kg)
The electric field intensity along the positive y axis
, can be given by the formula:

When light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
To find the answer, we have to know about the rules followed by drawing ray-diagram.
<h3>What are the rules obeyed by light rays?</h3>
- If the incident ray is parallel to the principal axis, the refracted ray will pass through the opposite side's focus.
- The refracted ray becomes parallel to the major axis if the incident ray passes through the focus.
- The refracted ray follows the same path if the incident light passes through the center of the curve.
Thus, we can conclude that, when light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
