Reflection and Image Formation Concepts

This lesson, led by teacher Marian Soriano, explores the concepts of light and mirrors. It covers the types of mirrors, including plane and spherical mirrors, and explains how light rays reflect off surfaces. The lesson delves into the law of reflection, the magnification equation, and the differences between specular and diffuse reflection. Students learn about the characteristics of images formed by mirrors, including virtual and real images, and engage in practice exercises to apply these concepts.

What is the primary function of a mirror?

• To emit light

• To absorb light

• To reflect an image

• To refract light

Which type of mirror has a flat reflective surface?

• Concave mirror

• Convex mirror

• Spherical mirror

• Plane mirror

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

• Angle of deviation

• Angle of incidence

• Angle of refraction

• Angle of reflection

According to the law of reflection, what is true about the angle of incidence and the angle of reflection?

• They are always different

• They are equal

• They are complementary

• They are supplementary

If the magnification of an image is less than 1, what does it indicate about the image?

• The image is inverted

• The image is larger than the object

• The image is the same size as the object

• The image is smaller than the object

What does a negative magnification value indicate about an image?

• The image is upright

• The image is virtual

• The image is inverted

• The image is larger than the object

What type of reflection occurs on a smooth surface?

• Diffuse reflection

• Specular reflection

• Irregular reflection

• Scattered reflection

Which type of image is always upright?

• Projected image

• Inverted image

• Virtual image

• Real image

What is the orientation of an image formed by a plane mirror?

• Smaller than the object

• Upright

• Inverted

• Larger than the object

Why is the word 'AMBULANCE' written in reverse on the front of an ambulance?

• To confuse other drivers

• To follow traffic regulations

• To be read correctly in a rear-view mirror

• To make it look stylish
