Light Reflection and Mirrors Concepts

The video tutorial explores how light reflects off surfaces, focusing on mirrors as excellent reflectors. It demonstrates how a dancer's reflection is visible only from certain angles using a mirror and camera setup. The science of reflection is explained, highlighting the angles of incidence and reflection. The tutorial concludes with practical applications, showing how light reflects at specific angles, affecting visibility.

Which of the following is NOT a good reflector of light?

• Still water

• Polished metal

• Rough wood

• Glass

What is used in the experiment to investigate how light is reflected?

• A dancer, a television camera, and a mirror

• A dancer, a flashlight, and a mirror

• A dancer, a television camera, and a flashlight

• A television camera, a flashlight, and a mirror

Why is the dancer's reflection only visible from certain camera positions?

• Because the mirror is not clean

• Because light reflects at specific angles

• Because the camera is not focused

• Because the dancer is moving

What is the ray of light called that approaches the mirror?

• Refracted ray

• Reflected ray

• Incident ray

• Scattered ray

What happens to light when it hits a mirror?

• It changes color

• It passes through

• It gets reflected

• It gets absorbed

What is the angle between the incident ray and the normal called?

• Angle of reflection

• Angle of deviation

• Angle of refraction

• Angle of incidence

What is the angle between the reflected ray and the normal called?

• Angle of refraction

• Angle of incidence

• Angle of reflection

• Angle of deviation

What remains the same for each ray of light when it is reflected?

• The color of the light

• The angle of incidence and reflection

• The speed of the light

• The intensity of the light

Why doesn't light bounce off the mirror at just any angle?

• Because the mirror is dirty

• Because the light is too weak

• Because the mirror is not flat

• Because of the law of reflection

What must the camera do to make the dancer visible?

• Zoom in on the dancer

• Move to the correct position

• Change its lens

• Increase its brightness
