Question 1 of 10
1. Question
The following statements about electromagnetic radiation are false except for?
Correct
Electromagnetic radiation is an electric and magnetic disruption in space. It produces waves that travel at light speed and is commonly known in the form of microwaves, infrared, radio waves, UV light, x-ray, and gamma rays.

Question 5 of 10
5. Question
Which of the following statement best defines light?
I. Light does not need a medium.
II. Light is an electromagnetic wave.
III. Light does not interact with a medium.
IV. Light displays both wave and particle properties.Correct
Option I, II and IV give the best definition. Light does not need a medium that results in electromagnetic interactions. It displays both wave and particle properties and when light interacts with a medium at its atomic level, it is absorbed by electrons that result in vibrations.
Incorrect

Question 6 of 10
6. Question
Which of the following statements best describes wave or particle duality?
Correct
Wave or particle duality is the display of both wave and particle properties of x-ray and gamma rays. This helps in understanding radiant energies and how they interact with matter.
Incorrect
Wave or particle duality is the display of both wave and particle properties of x-ray and gamma rays. This helps in understanding radiant energies and how they interact with matter.

Question 7 of 10
7. Question
Select which statement(s) about light/light rays is true.
I. Light can travel through various media at various speeds.
II. Light’s refraction varies from how the transition occurred.
III. Light changes in the speed of a wave.
IV. Light bounces back from the barrier.Correct
The true statements are I and II. Light can travel through various media at various speeds, refracting depends on how fast or slow waves have transitioned through its medium. Refraction refers to the change of speed wave, reflection refers to the light waves bouncing back from a barrier between two media.
Incorrect
The true statements are I and II. Light can travel through various media at various speeds, refracting depends on how fast or slow waves have transitioned through its medium. Refraction refers to the change of speed wave, reflection refers to the light waves bouncing back from a barrier between two media.

Question 8 of 10
8. Question
Which of the following statement best describes the difference between reflection and refraction?
Correct
Refraction refers to the bending of a wave as it goes through an angle of one medium to another varying and depending on the speed of propagation. Reflection refers to the light waves bouncing back from a barrier between two media.
Incorrect
Refraction refers to the bending of a wave as it goes through an angle of one medium to another varying and depending on the speed of propagation. Reflection refers to the light waves bouncing back from a barrier between two media.

Question 9 of 10
9. Question
Which of the following statements best describes the law of reflection?
Correct
The law of reflection states that the incidence angle must be equivalent to the angle of reflection when a disturbed wave has reflected at a barrier of a medium.
Incorrect
The law of reflection states that the incidence angle must be equivalent to the angle of reflection when a disturbed wave has reflected at a barrier of a medium.
