Q1 · Light — Reflection and Refraction · EASY
A concave mirror has a focal length of 15 cm. An object is placed 45 cm in front of the mirror. What is the position of the image formed?
Q2 · Light — Reflection and Refraction · MEDIUM
A ray of light traveling in air enters a glass block at an angle of incidence of 60 degrees. If the refractive index of glass is 1.5, what is the angle of refraction inside the glass? (Given: sin 60° = 0.866, sin 30° = 0.5, sin 35° = 0.574)
Q3 · Light — Reflection and Refraction · HARD
A convex lens forms a real, inverted image of the same size as the object. If the distance between the object and the image is 80 cm, what is the focal length of the lens?
Q4 · Light — Reflection and Refraction · HARD
A ray of light is incident on a plane mirror at an angle of 35° to the mirror surface. What is the angle of reflection measured from the normal?
Q5 · Light — Reflection and Refraction · MEDIUM
A concave mirror has a focal length of 20 cm. An object is placed 30 cm from the mirror. What is the nature and position of the image formed?
