What is true about X-rays and microwaves?

1 answer:

7 0

I believe the correct answer from the choices listed above is option C. X-rays have greater frequency than microwaves. In a electromagnetic spectrum, the order in increasing frequency is as follows:

radio waves,microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation,X-rays and gamma rays.

Friction can be bad by being too strong or too weak.

Sometimes, when it is too strong, it decreases efficiency since some energy is wasted and turns to heat. Friction can also damage equipment/objects like when you slide it on the floor.

When friction is too weak, like for instance when there is black ice- our center of gravity is displaced too quickly and we can fall. Likewise, if there is a lot of slush on the ground, cars can slip and slide.

A metallic sheet has a large number of slits, 5.0 mm wide and 20 cm apart, and is used as a diffraction grating for microwaves.

To solve this problem it is necessary to apply the concepts related to the principle of superposition and constructive interference, that is to say everything that refers to an overlap of two or more equal frequency waves, which when interfering create a new pattern of waves of greater intensity (amplitude) whose cusp is the antinode.

Mathematically its definition can be given as:

$d sin\theta =m\lambda$
