Absorption Noun

---

[ab-sorp-shuhn]

Back

Absorption

---

The process by which a material takes in light energy, converting it into other forms of energy like heat.

---

Example: The image shows an apple absorbing other colors of light and reflecting red, illustrating light absorption.

Front

Transmission Noun

---

[trans-mish-uhn]

Back

Transmission

---

The passing of light waves through a material without the light being absorbed or reflected by that material.

---

Example: Light passes through clear glass, showing transmission without absorption or reflection.

Front

Transparent Adjective

---

[trans-pair-uhnt]

Back

Transparent

---

Describes a material that transmits most of the light that strikes it, allowing for clear viewing of objects behind it.

---

Example: Light passes through transparent glasses, showing how transparent materials allow clear viewing.

Front

Translucent Adjective

[trans-loo-suhnt]

Back

Translucent

---

Regular Reflection Noun

---

[reg-yuh-ler ri-flek-shuhn]

Back

Regular Reflection

---

Example: Light rays hitting a smooth mirror reflect at equal angles, showing regular reflection.

Front

Diffuse Reflection Noun

---

[dih-fyoos ri-flek-shuhn]

Back

Diffuse Reflection

---

Reflection from an uneven surface where parallel light rays are scattered in many different directions, preventing a clear image.

---

Example: Parallel light rays hit a rough surface and scatter in different directions, illustrating diffuse reflection.

Front

Mirror Noun

---

[mir-er]

Back

Mirror

---

Example: Light rays hitting a smooth surface reflect in a regular pattern, showing how mirrors work.
