Lenses and Snell's Law

Classify the image formed in this scenario.

• real, inverted, larger than original

• real, inverted, smaller than original

• virtual, upright, larger than original

• virtual, upright, smaller than original

The point where the rays meet is known as....

• Fire
• the focal point
• refraction
• Plane of the lens

A diverging lens is also known as a ____lens.

• refracted
• diffracted
• convex
• concave

The focal length of the lens in your eye is about 0.015 m. If the object is 1 m from your eye, where is the image produced? 

• 0.0315 m
• 0.0243 m
• 0.0152 m
• 0.0601 m

The ray diagram when the object is placed on the focal point shows no image. Why is no image formed?

• Because the principal rays intersect on the virtual side of the lens.

• Because the principal rays are parallel to each other.

• Because the principal rays are perpendicular to each other.

• Because convex lenses cannot form images.

Which one is a convex lens?

• A
• B

Light travels from air (n = 1.00) into a "mystery" material. The incident ray of light hits the surface at angle of 43^o and the refracted ray enters the mystery material at an angle of 27^o. What is the index of refraction of the mystery material? n₁sin(Θ₁) = n₂sin(Θ₂)

• 1.0

• 0.67

• 2.1

Light travels from air (n = 1.00) into a second material. The incident ray of light hits the surface at angle of 64^o and the refracted ray enters the second material at an angle of 32^o. What is the index of refraction of the second material? n₁sin(Θ₁) = n₂sin(Θ₂)
