Question 11: The light that bends as it passes through a raindrop is an example of refraction. Refraction is a phenomenon wherein it is being deflected or being bent while passing through the interface of one medium to another. In this specific scenario, when the light ray is entering the drop, it is being refracted or bent into an angle that depends on its wavelength.

Question 12: The least dangerous type of electromagnetic wave in the human body are microwaves. This is because microwaves are just short-wavelength radio waves and are not considered as harmful if exposed in small volumes. However, since this is still considered as an electromagnetic radiation, long-term exposure may still pose adverse effects on one’s health, though not as destructive as the other types of electromagnetic waves.

Question 13: Light travels fastest through outer space. This is mainly because outer space is considered as a vacuum. It has a very low density and pressure levels since it is lacking matter, hence, giving enough space for light to travel faster. Unlike the other options which are denser, outer space is the best place for light to travel the fastest.

Question 14: The waves that have shorter wavelengths than visible light are ultraviolet waves and gamma rays. This is based on the electromagnetic spectrum. Electromagnetic (EM) spectrum is the range of wavelengths and frequencies and is largely divided into seven (7) regions, from decreasing wavelength in the left and increasing frequency and energy to its right. Visible light is in the middle of the electromagnetic spectrum and has a wavelength of about 740 nanometer to 380 nanometer. Ultraviolet waves have a wavelength of 380 nanometer to about 10 nanometer, while gamma rays have a wavelength of less than 100 petameters.
