Answer:
Explanation:
Since X-rays are high (energy) frequency photons and radio waves are composed of low (energy) frequency photons, X-rays are more energetic and can do more harm to organic materials (such as cells).
I think this is the right order.
1.Make an observation
2.Ask a question
3.Develop a hypothesis
4.Experiment or test idea
5.Analyze data
6.Develop a theory
7.Draw conclusions

(a) The labelled diagram is shown.
(b) The refractive index of diamond is 2.42. Refractive index of diamond is the ratio of the speed of light in air to the speed of light in diamond.i.e.,
μ=
Speedoflightindiamond
Speedoflightinair
and, the ratio of these velocities is 2.42. i.e., This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is
1/2.42
times the speed of light in vacuum.
Explanation:
a) Draw and label the diagram given :
(i) Incident ray
(ii) Refracted ray
(iii) Emergent ray
(iv) Angle of reflection
(v) Angle of deviation
(v) Angle of emergence
(b) The refractive index of diamond is 2.42. What is the meaning of this statement in relation to speed of light?
B
Think of inertia of getting into a car accident without a seat belt although the car stops you will not you would likely fly out the window
