What we verified before publishing

Fact-check status: skipped

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

In NCERT Class 8 Science Chapter 16, light is introduced as something that makes objects visible when it enters our eyes after being emitted or reflected by objects.
The chapter states that the two laws of reflection are that the angle of incidence equals the angle of reflection and that the incident ray, reflected ray, and normal lie in the same plane.
An incident ray is the ray of light that strikes a surface, and a reflected ray is the ray that bounces back from the surface.
Regular reflection occurs on smooth, polished surfaces, while diffused or irregular reflection occurs on rough surfaces.
The NCERT chapter explains that multiple images can be formed when light is reflected more than once.
Sunlight is described as white light that consists of seven colours.
Dispersion is the splitting of light into its constituent colours.

Heads up: opening this section reveals every question, every option, and the correct answer for this round. If you came here to play, scroll up and hit Play first.

Question 1: What makes objects visible to our eyes?

Light entering the eyes ✓ correct
Darkness
Only emitted light
Sound waves

Explanation: Objects become visible when light emitted or reflected by them enters our eyes, allowing us to perceive the world around us.

Question 2: What is the angle of reflection equal to?

Zero degrees
90 degrees
Angle of incidence ✓ correct
Angle of refraction

Explanation: According to the laws of reflection, the angle of incidence is always equal to the angle of reflection on a smooth surface.

Question 3: What do we call the ray of light that strikes a surface?

Normal ray
Reflected ray
Dispersion ray
Incident ray ✓ correct

Explanation: The incident ray is the ray of light that strikes a surface, while the reflected ray is the one that bounces back.

Question 4: Which surface causes regular reflection?

Cardboard
Wall
Polished, smooth surface ✓ correct
Rough surface

Explanation: Regular reflection happens when light hits a super smooth, polished surface like a mirror, causing all rays to bounce off in the same direction, creating a clear image!

Question 5: What happens when light is reflected more than once?

No image forms
Only one image forms
Multiple images form ✓ correct
Light disappears

Explanation: Multiple images can be formed when light is reflected more than once, which is a principle used in devices like kaleidoscopes.

Question 6: How many colours make up white sunlight?

Ten
Five
Seven ✓ correct
Three

Explanation: Sunlight is described as white light that consists of seven distinct colours, which can be separated through the process of dispersion.

Question 7: What is the splitting of light into colours called?

Reflection
Absorption
Refraction
Dispersion ✓ correct

Explanation: Dispersion is the scientific term for the splitting of white light into its constituent colours, such as when passing through a prism.

Question 8: Which part of the eye controls the size of the pupil?

Cornea
Retina
Iris ✓ correct
Optic nerve

Explanation: The iris is the coloured part of the eye that controls the size of the pupil, adjusting it based on the available light.

Question 9: What happens to the pupil in dim light?

It becomes large ✓ correct
It disappears
It becomes small
It turns white

Explanation: In dim light, the pupil becomes large to allow more light to enter the eye, helping us see better in darker conditions.

Question 10: What system helps visually impaired persons read?

Binary code
Morse code
Sign language
Braille ✓ correct

Explanation: The Braille system is a tactile writing system used by visually impaired persons to read and write using raised dots.
