It's any wave that repeats over and over and over and over and over and over and over and over and over and over, AND . . .

-- each one has the same shape

-- each one has the same amplitude

-- each one takes the same length of time.

Types of waves. ... A pulse is a single disturbance while a periodic wave is a continually oscillating motion. There is a close connection between simple harmonic motion and periodic waves; in most periodic waves, the particles in the medium experience simple harmonic motion

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.

A weight lifter lifts a 1.0 x 103 N weight 1.5 m in 2.0 s. The power is?
viktelen [127]

Answer:

750W

Explanation:

Given parameters:

Weight = 1 x 10³N = 1000N

Distance  = 1.5m

Time  = 2s

Unknown:

Power = ?

Solution:

Power is the rate at which work is done

  Work is the force applied on a body to move it through a particular distance

         Work = force x distance

            Power = \frac{work}{time}

Now, work = 1000 x 1.5 = 1500J

So;

     Power  = \frac{1500}{2}   = 750W
