  4. jaune
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The color yellow is known as 'jaune' in French. This is a basic color word that every French learner must know. 'Noir' means black, 'rouge' means red, and 'marron' means brown. French color words are essential adjectives that usually follow the noun they describe, like 'une voiture jaune' (a yellow car).

Color of light emited by Neon gas is..

  1. Blue

  2. Red

  3. Green

  4. Pink
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Neon gas emits a characteristic red-orange glow when electrically excited due to its atomic emission lines. The primary wavelength emitted by neon is around 640 nanometers (red), which is why neon signs have their distinctive red appearance. Other colors in 'neon signs' are achieved by using different gases or phosphor coatings.

Color of light emited by Helium gas is..

  1. Pinkish-red

  2. Green

  3. Sky Blue

  4. Lavender
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Helium gas, when electrically excited, emits light in the pinkish-red to yellow-orange range depending on the pressure and conditions. The characteristic helium discharge color is often described as pinkish-red or peach-colored due to the combination of spectral lines including red, yellow, and green wavelengths. This is visible in helium-neon lasers and discharge tubes.

Color of light emited by Argon gas is..

  1. White

  2. Red

  3. Yellow

  4. Light Blue

  5. Orange
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Argon gas emits a pale lavender-blue to violet light when electrically excited, due to its dominant emission lines in the blue-violet spectrum (around 420 nm and 470 nm). This color is commonly seen in argon-filled discharge tubes and is why argon is often used in combination with other gases to achieve different lighting effects. The 'Light Blue' option is the closest approximation among the choices.

Color of light emited by Xenon gas is..

  1. White

  2. Light Blue

  3. Lavender

  4. Green
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Xenon gas, when electrically excited, emits a characteristic lavender to blue-white light due to its broad emission spectrum across multiple wavelengths. This property makes xenon useful in high-intensity discharge lamps, flash photography, and automotive headlights. The lavender description captures the dominant hue in the visible spectrum of xenon emission.

Color of light emited by Krypton gas is..

  1. White

  2. Pink

  3. Magenta

  4. Sky Blue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Krypton gas emits white light when electrically excited because it produces a continuous spectrum with multiple wavelengths across the visible range. This balanced emission creates a nearly pure white light, which is why krypton is used in high-performance flash photography and specialized lighting applications where color accuracy is important. White light appears when all visible wavelengths are present in roughly equal proportions.
