Provide definitions for each of the following terms: a. Luminous b. Wavelength c. Frequency d. Refraction - Bending of light as it passes from one transparent medium to another

here are the definitions for your classwork:

1. Provide definitions for each of the following terms:

• a) Luminous: A luminous object is one that produces its own light.

  $$\boxed{\text{An object that emits its own light.}}$$

• b) Wavelength: Wavelength ($\lambda$) is the spatial period of a periodic wave, the distance over which the wave's shape repeats. It is typically measured from crest to crest or trough to trough.

  $$\boxed{\text{The distance between two consecutive corresponding points on a wave.}}$$

• c) Frequency: Frequency ($f$) is the number of complete wave cycles or oscillations that pass a given point per unit of time. It is measured in Hertz (Hz).

  $$\boxed{\text{The number of complete wave cycles that pass a point per unit of time.}}$$

• d) Refraction: Refraction is the bending of light as it passes from one transparent medium to another, which occurs due to a change in the light's speed.

  $$\boxed{\text{The bending of light as it passes from one transparent medium to another due to a change in its speed.}}$$
