1). While I'm driving the car, I keep my eyes pointed out the front window,

so that LIGHT WAVES coming straight in through the front window get into

them. Using this process, I'm able to SEE what's in front of me, so that I don't

drive straight into it.


2). Also while I'm driving the car, I usually have the radio on, and I tune it

to a frequency where the RADIO WAVES that it responds to are being

modulated by people who are either talking or else playing classical music.


3). Before I leave the house on most days, I take a small container of

frozen Irish oatmeal out of the freezer, and I load it into the big box

above the stove, where MICROWAVE ENERGY thaws it, and warms

it to a nice eating temperature.


3A). When I arrive at my job, I usually do things that are also associated

in some way with MICROWAVE energy, since I work as a microwave

system design engineer. Most of the time it's just paperwork, but there

ARE times when I work with an actual radio that's either generating or

detecting real microwave energy, and either sending it up to, or receiving

it down from, a big dish antenna on a radio tower. Those are the days that

I like the best.

We can see our face clearly on mirror why cant we see our face clear on aluminium or irion plate
Simora [160]

Because specular reflection occurs with a mirror, while diffuse reflection occurs with aluminium or iron plate

Explanation:

Reflection is a phenomenon typical of waves (such as light wave), that occurs when a wave bounces off the surface of a certain material, going back into the original medium at a certain angle, without changing speed, frequency or wavelength.

The direction of the reflected ray is given by the law of reflection, which states that:

  • The incoming ray, the reflected ray and the normal to the surface all lie on the same plane
  • The angle of incidence is equal to the angle of reflection

Depending on the type of surface, two different types of reflection can occur:

  • Specular reflection: this occurs when the surface is perfectly smooth. In such a case, all the incoming rays of light hit the surface with same angle of incidence, therefore they are reflected at the same angle. This means that a perfect and clear image of the original object can be formed: this is the case of a mirror.
  • Diffuse reflection: when the surface is not smooth, the imperfections on the surface are such that the incoming rays of light hit the surface at different angles of incidence. As a result, the rays are reflected at different angles to each other, and therefore no clear image of the object is produced. This is the case of aluminium or iron plate.

When you stretch a spring 33 cm past its natural length, it exerts a force of 6 N. What is the spring constant of this spring?
PilotLPTM [1.2K]

The spring formula:

       Force =  - (spring constant) · (distance stretched or squashed)

          
6 N  =  - (spring constant) · (33 cm)

                   =  - (0.33 m) · (spring constant)

          Spring constant  =   - (6 N) / (0.33 m)

                                      =    - 18.18 N/meter .

The negative signs means that the spring always wants to go in the
opposite direction from where you forced it, and return to its relaxed
length.  If you stretch it, it tries to get shorter, and if you compress it,
it tries to get longer.

How do the interactions between the two atoms change when the atoms get closer than the balanced point?
ValentinkaMS [17]

Answer:

The strong attraction of each shared electron to both nuclei stabilizes the system, and the potential energy decreases as the bond distance decreases. If the atoms continue to approach each other, the positive charges in the two nuclei begin to repel each other, and the potential energy increases.
