It reasonable to treat light as a ray instead of a wave in everyday situations because "the wavelengths of light are so short that they wave effects are negligible".

<h3>What is wavelength of light?</h3>

The distance between the two crests or troughs of the light wave is known as the wavelength of light. Using the Greek letter lambda , it is identified. As a result, wavelength refers to the separation between one wave's crest or dip and the following wave.

Some properties of wavelength of light are-

  • The wavelengths and frequency of these distinct light colors vary.
  • The visible spectrum's longest wavelength and lowest frequency are found in red light.
  • The visible spectrum's violet color has the shortest wavelength and highest frequency.
  • A small band of wavelengths, roughly 380 to 730 nm, make up visible light.
  • Our eyes interpret these wavelengths as various hues.
  • If only one wavelength or a small range of wavelengths are seen, they are perceived as having a specific hue.

The four properties of light waves are-

  • reflection,
  • refraction,
  • diffraction and
  • interference.

bulgar [2K]

Answer:

Emily's opportunity cost of producing 1 milkshake is 1 ice cream sundae.

Ben's opportunity cost of producing 1 milkshake is​ 0.5 ice cream sundae.

Explanation:

Both Emily and Ben own an ice cream parlor.

In an hour Emily can produce 40 milkshakes or 40 ice cream sundaes.

Emily's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{40}{40}

= 1 ice cream sundae

In an hour Ben can produce 20 milkshakes or 10 ice cream sundaes.

Ben's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{20}{10}

= 0.5 ice cream sundae

We see that Ben has a lower opportunity cost of producing milkshake, so we can say that he has a comparative advantage in producing milkshake.

Why did coastal city-states develop in East Africa?
ycow [4]
Bantu civilization developed city-states along the East coast, which were soon involved in the bustling Indian Ocean trade. These city-states developed independently and remained that way, trading East African resources, pottery, and slaves. In the process, most of these cities also adopted Islam as their religion.
