_______ is the behavior that ensues when a wave encounters an obstacle or must pass through an opening.
Transmission
Absorption
Reflection
Diffraction
During a routine eye examination, a vision test is given. This test will tell the eye doctor exactly what prescription is needed for glasses or contact lenses. Normally, a value of 20/20 is considered perfect vision. Individuals who can read letters that are 3/8 of an inch tall from at least 20 feet away would have 20/20 vision. If an induvial does not have 20/20 vision, they have what is called a'refractive error".
What causes this refractive error?
The light is not being reflected from the lens of the eye.
The light is not being absorbed when it hits the lens of the eye.
The light is not being transmitted when it passes through the lens of the eye.
The light is not bending properly when it passes through the lens of the eye.
Demonstrate the correct order of electromagnetic waves from LOWEST to HIGHEST frequency.

What technology has allowed scientists to process sound waves by tracking how the waves bounce off nearby objects and reflect back to the original source of the sound?
