may vary depending on the organization.
Answer:
15.Radiowave
16.laser is device that generates an intense beam of other electromagnetic radiation by emission of photons from excited atoms.
17.this is a laboratory instrument commonly used to display and analyse the waveformof electronic signals.
19. this is a space entirely devoid of matter.
Answer:
4.875 V
Explanation:
N = 1300
diameter = 2.10 cm
radius = half of diameter = 1.05 cm
B1 = 0.130 T
B2 = 0 T
t = 12 ms
According to the law of electromagnetic induction,
Where, Ф be the magnetic flux linked with the coil
e = 4.875 V
<span>Answer: option B. The ability to transmit light; for example water. The transparency is due to the pass of the light. The pass of light is what is called transmission of light. Light may be reflected, refracted or transmitted. Remember light is combination of several waves with different frequencies. When light falls upon an object the interaction may be some frequencies are reflected and other transmitted. Transparent objects are those that permit tha pass of (transmit) most light waves and so let the eyes and instruments to see through them.</span>
Light acts like a wave and particle.
If there is an experiment designed to detect waves, you will see light as waves.
Similarly, if you set up an experiment to detect particles, you will see light as particles.
Basically, how you see light depends on the circumstances.
