Answer:
Interference of light
Diffraction of light
Polarization of light
Reflection of light
all show the wave nature of light.
Answer:
0 J
Explanation:
As work is force times displacement, if no displacement occurs, no work occurs.
Answer:
f = q
Explanation:
In the attachment we can see a diagram of the parallel rays.
The dotted line represents the normal to the mirror surface
These rays when reflected using the constructor equation
where p and q are the distance to the object and the image respectively.
Since the rays are parallel P = inf
1 / f = 1 / inf + 1 / q
f = q
this means that all the rays focus on one focal point.
A MAGNET IS A MATERIAL OR OBJECT THAT PRODUCES A MAGNETIC FIELD
