Light Facts & Worksheets For Kids | Theories & Speed Of Light - Free Printable

It looks like the image you've uploaded is a worksheet titled "COLORS OF LIGHT" from KidsKonnect.com, designed to teach students about the visible spectrum of light, including wavelength, frequency, photon energy, and color.

However, there's an issue: all the rows in the table have identical values:

- Wavelength: 350–480 nm
- Frequency: 668–789 THz
- Photon Energy: 2.75–3.26 eV

And all six rows are asking for the same color corresponding to this range.

🔍 Let's solve it step by step.

---

✔ Step 1: Understand the Wavelength Range

The wavelength range given is 350–480 nanometers (nm).

Let’s break that down:

- 350–400 nm: Ultraviolet (UV) — *not visible to the human eye*
- 400–450 nm: Violet
- 450–480 nm: Blue

So, 350–480 nm includes:
- Ultraviolet (350–400 nm) → Invisible
- Violet (400–450 nm) → Visible
- Blue (450–480 nm) → Visible

But since the visible portion starts at ~400 nm, the visible colors in this range are:
> 🟣 Violet and 🔵 Blue

However, because 350–480 nm spans both UV and visible light, and the visible part is violet to blue, the dominant color associated with this range is:

> ✔ Violet / Blue

But more precisely, the color perceived when light is in the 350–480 nm range depends on where in the spectrum it falls.

In standard visible light:
- ~400–420 nm → Violet
- ~420–450 nm → Blue-Violet
- ~450–480 nm → Blue

So, the color corresponding to 350–480 nm (especially the visible part) is:

> ✔ Violet to Blue

But since the highest end is 480 nm, which is blue, and 400–480 nm is generally referred to as violet-blue, we can conclude:

> 🎨 The color for 350–480 nm is Violet and Blue — but since violet starts at ~400 nm, and the range goes up to 480 nm, the primary visible color is Violet at the lower end and Blue at the upper end.

But note: 350–400 nm is UV, not visible.

So, if we're talking about visible light, the correct answer for wavelengths between 400–480 nm is:

> ✔ Violet (400–420 nm), then Blue (420–480 nm)

But the worksheet says 350–480 nm, which includes invisible UV.

Since the question asks: *"what color corresponds to each wavelength"*, and the range includes both UV and visible, we must clarify.

---

🧠 Key Point:

- Human eyes cannot see wavelengths below ~400 nm.
- So, 350–400 nm is ultraviolet → not visible.
- Only 400–480 nm is visible → Violet to Blue.

Therefore, for the visible part, the color is:

> ✔ Violet and Blue

But since the entire range is listed as 350–480 nm, and the visible portion is violet-blue, the most accurate answer for the color in this range is:

> 🟣 Violet (at 400–420 nm)
> 🔵 Blue (at 450–480 nm)

But since all entries are the same, and the task says "color each panel", and there are six panels, perhaps the intention was to have different ranges, but they were duplicated.

---

✘ Problem:

All six rows are identical, so unless there's a typo, the answer for all six would be the same.

But based on scientific data:

> ✔ Color: Violet to Blue

So, for each panel, you should color it using violet and blue shades, or just blue, depending on interpretation.

---

✔ Recommended Answer for Each Panel:

> Color: Violet / Blue
> *(Use a blend of purple/violet and blue in coloring)*

---

✔ Definitions (Bottom of Worksheet):

#### 1. Wavelength:
> The distance between two consecutive peaks (or troughs) of a wave. In light, it determines the color we see. Measured in nanometers (nm).

#### 2. Frequency:
> The number of wave cycles that pass a point per second. For light, it is measured in terahertz (THz). Higher frequency means higher energy.

#### 3. Photon Energy:
> The energy carried by a single particle of light (photon). It is directly proportional to frequency and inversely proportional to wavelength. Measured in electron volts (eV).

✔ Final Answer Summary:

| Wavelength | Frequency | Photon Energy | Color |
|-----------|-----------|---------------|-------------|
| 350–480 nm | 668–789 THz | 2.75–3.26 eV | Violet to Blue |

> ⚠️ Note: The 350–400 nm part is ultraviolet (invisible), so only 400–480 nm is visible. Therefore, the visible color is Violet (400–420 nm) and Blue (420–480 nm).

---

✔ How to Color the Panels:

- Use purple/violet for the lower end (~400 nm)
- Gradually shift to blue for the upper end (~480 nm)
- Or simply color each panel blue-violet or lavender-blue

---

✔ Conclusion:

Even though the worksheet has repeated rows, the correct answer for 350–480 nm (visible portion) is:

> ✔ Violet and Blue

You should color each panel with a violet-blue shade.

And define the terms as above.
