Step-by-step solution for: Light properties worksheet
It looks like you've shared a worksheet with multiple-choice questions related to light, energy, and electromagnetic radiation. Since I can't watch videos or access external content (like the YouTube link provided), I’ll answer the questions based on scientific knowledge.
Let’s go through each question one by one and provide the correct answers with explanations:
---
1. What is a light?
a) Kind of energy
b) A rays of light
✔ Correct answer: a) Kind of energy
Explanation: Light is a form of electromagnetic energy that travels in waves. It is not just "rays" — rays are a way we represent light directionally, but fundamentally, light is energy.
---
2. How travel the light?
a) In energy
b) In waves
✔ Correct answer: b) In waves
Explanation: Light travels in waves. It exhibits wave-like properties such as diffraction and interference. Light also behaves as particles (photons), but in this context, "in waves" is the best answer.
---
3. What is energy made of?
a) Heated up or gains
b) Molecules
✘ Neither option is fully accurate, but let's analyze:
- Energy is not "made of" molecules; molecules have energy.
- Energy is not something that is "heated up or gains" — that's vague and incorrect phrasing.
However, if we must choose from these two, neither is scientifically correct, but perhaps the intended answer was meant to be something like "motion or position" (kinetic/potential energy). Given the options, none are ideal, but b) Molecules might be interpreted loosely as "energy is associated with molecules," which is misleading.
But since it's a multiple-choice quiz, possibly b) Molecules is expected as a weak choice — though not accurate.
✔ Best possible choice (though flawed): b) Molecules
⚠️ Note: This question is poorly worded. Energy is not "made of" molecules — rather, molecules possess energy due to motion, bonds, etc.

4. Examples of electronic radiation.
a) Microwaves, x-rays
b) Gamma rays, natural light
✔ Correct answer: a) Microwaves, x-rays
Explanation: Electromagnetic radiation includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
- Microwaves and X-rays are examples of electromagnetic radiation.
- "Natural light" is vague — sunlight contains many types of radiation, but "natural light" isn’t a scientific term for radiation type.
So a) is better.

5. What is the most important light of earth?
a) Moon
b) Sun
✔ Correct answer: b) Sun
Explanation: The Sun is the primary source of light and energy for Earth. The Moon reflects sunlight — it does not produce its own light.
---
6. How is made a rainbow?
a) When water droplets in plastic and bags in prism
b) When water droplets in the air bend sunlight
✔ Correct answer: b) When water droplets in the air bend sunlight
Explanation: Rainbows are formed when sunlight enters water droplets in the atmosphere, refracts (bends), reflects inside the droplet, and disperses into different colors. The process involves refraction, reflection, and dispersion.
Option a) is confusing and nonsensical ("plastic and bags in prism") — likely a typo or error.
---
7. How many colors has the rainbow?
A) 9 colors
b) 7 colors
✔ Correct answer: b) 7 colors
Explanation: A rainbow typically has seven main colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV). While there are infinite shades, the traditional model teaches 7 distinct colors.
---
8. What is the definition of infrared light?
a) Light with a longer wavelength than the reddest visible light
b) Light with a longer wavelength that pass in our eyes
✔ Correct answer: a) Light with a longer wavelength than the reddest visible light
Explanation: Infrared light has wavelengths longer than visible red light but shorter than microwaves. It is invisible to the human eye (so “passes in our eyes” is false).
Option b) is incorrect because infrared light cannot be seen by the human eye.
---
1. a) Kind of energy
2. b) In waves
3. b) Molecules *(Note: Poorly worded question)*
4. a) Microwaves, x-rays
5. b) Sun
6. b) When water droplets in the air bend sunlight
7. b) 7 colors
8. a) Light with a longer wavelength than the reddest visible light
