-- In the microwave oven, the cavity (cooking chamber) is intentionally shaped

to take advantage of reflection from the walls and create the desired pattern of

standing waves inside the box.

-- In microwave communication, signal energy reflected from buildings, atmospheric

layer boundaries, ponds or wet grass, can be re-directed toward the receiving antenna,

and combine with the direct signal when both arrive there. Since the reflected path is

longer than the direct path, the two signals arrive at the receiver out of phase, and their

combined intensity depends on the phase difference. The sum may be anything between

zero (complete loss of signal) and double the normal received level.

How the light Law of Reflection works on the reflector?

The law of reflection states that the angle of incidence is equal to the angle of reflection. In the case of a reflector, when light rays hit the surface, they bounce off at an angle equal to the angle at which they hit the surface. This property is used in designing reflectors to control the direction of reflected light.


What happened to amplitude when wave reflected?

When a wave is reflected, the amplitude remains the same if there is no energy loss in the reflection process. However, if there is energy loss during reflection, the amplitude may change as some of the energy is absorbed or dissipated.


Examine what happens when waves are reflected from a parabolic reflector?

When waves are reflected from a parabolic reflector, they are focused towards a single point called the focal point. This phenomenon is known as "collimation," where the reflected waves become parallel to each other. Parabolic reflectors are commonly used in applications such as satellite dishes and telescopes to collect and concentrate waves at the focal point.


How does reflection work in car headlights?

Reflection in car headlights occurs when light from the bulb hits the reflective surface inside the headlight housing, known as a reflector. This reflector is designed to bounce the light forward, creating a focused beam that illuminates the road in front of the car. The shape and material of the reflector are carefully designed to optimize the distribution and intensity of the light output.


Can an object be both a good absorber and good reflector at the same time why or why not?

No, you can be both good and evil. This is the same concept. The object is either a good absorber or a good reflector, and can not be both. Black is a good absorber, white is a good reflector.

What two types antenna used for terrestrial microwave communication?

Virtually all terrestrial microwave communication is point-to-point, using parabolic reflector antennas. A small percentage uses yagi, helical, corner reflector, or flat-plate reflector antennas. Essentially no "omnidirectional" antennas are used in microwave.

How do you use reflect as a noun?

The noun forms of the verb to reflect are reflector, reflection, and the gerund, reflecting.Example sentences for nouns:I have a reflector on the back of my bicycle.He stopped to look at his reflection in the store window.The incident gave us cause for reflecting.


Why might a parabolic reflector horn type microwave antenna be preferable to a parabolic dish type microwave antenna?

The reflector horn type antenna has greater "side lobe" rejection, directionality and sensitivity (efficiency) than a dish type.


What is the observation in a direction of light rays ata smooth reflector?

What is the noun from of reflects?

How could soundwaves be focused by using reflection?

Not all sound that hits matter is absorbed. Some of it is reflected. That means sound bounces off the solid matter the way a tennis ball bounces off a wall. Sound reflected back to its source is an echo.


Which verb does noun reflect come from?

The word 'reflect' is a verb (reflect, reflects, reflecting, reflected).The noun forms of the verb to reflect are reflector, reflection, and the gerund, reflecting.
