The bending of waves around the edge of a barrier is known asa. reflection.
b. refraction.
c. diffraction.
d. interference.

Answers

The answer is C. The bending of waves around the edge of a barrier is called diffraction. It is any phenomena which happens when a wave energy meets an obstacle or a slit. Examples of this are the tracks on a CD act as a grating to form a rainbow pattern in the disk, a hologram on a card, resolution limits on cameras and microscope.

The bending of waves around the edge of a barrier is known as diffraction (Option C)

How do i know which option is correct?

To know which option is correct, we shall define the given options. This is shown below:

Reflection of a wave is simply defined as the bounce back of a wave without a change in the properties of the wave

Refraction is the change in the properties of a wave as it travel from one medium to another.

Diffraction is a property of wave which is defined as the bending of light around the edge of obstacle or barriers.

Interference is the combination of waves to form an entirely different wave with either a reinforce or destructive displacement.

With the above definitions, we can conclude that the correct answer to the question is diffraction (option C)

How many miles can you get on one tank of gas if your tank holds 18 gallons and you get 22 miles per gallon?

Answers

Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following:
18 gallons * 22 miles / 1 gallon
Which simplifies to 18 * 22 miles = 396 miles.

Answer: 18*22=396

Explanation:

18*22=

(10*22) + (8*22)=

220+176=396
