Q 34. 1 Which of the following changes its focal length when it is immersed in water? 1. a concave mirror 2. a convex mirror three. a diverging lens 4. all of the above 5. none of the above
A 34. one Which of the following changes its focal length when it is immersed in water? one. a concave mirror ii. a convex mirror 3. a diverging lens 4. all of the above 5. none of the in a higher place
Q 34. ii A concave mirror with a radius of curvature of xx cm has a focal length of i. 40 cm 2. twenty cm iii. 10 cm 4. 5 cm 5. answer depends on the alphabetize of refraction of the air around the mirror
A 34. 2 A concave mirror with a radius of curvature of 20 cm has a focal length of 1. 40 cm two. 20 cm 3. 10 cm four. 5 cm 5. reply depends on the index of refraction of the air around the mirror
Q 34. iii An object is placed xv cm away from a concave mirror of focal length +xxx cm. The paradigm formed by the mirror is 1. real and larger than the object ii. real and smaller than the object 3. real and the same size as the object 4. virtual and larger than the object v. virtual and smaller than the object
A 34. 3 An object is placed 15 cm away from a concave mirror of focal length +30 cm. The epitome formed past the mirror is one. real and larger than the object 2. real and smaller than the object 3. existent and the same size as the object 4. virtual and larger than the object five. virtual and smaller than the object
Q 34. 4 A concave mirror forms a real paradigm of a lamp filament. If yous apply blackness paint to cover the lower half of the mirror, what part of the filament will be visible in the image? 1. only the upper half of the filament 2. only the lower half of the filament 3. only the left-hand half of the filament 4. just the right-hand half of the filament 5. the entire filament
A 34. 4 A concave mirror forms a existent image of a lamp filament. If you lot use black paint to cover the lower half of the mirror, what part of the filament will be visible in the image? ane. but the upper one-half of the filament two. but the lower half of the filament 3. simply the left-hand half of the filament 4. simply the right-hand half of the filament 5. the entire filament
Q 34. 5 A thin lens has focal length f = – 12 cm. If an object 9 cm tall is placed 24 cm from the lens, what is the acme of the epitome? 1. 27 cm tall 2. xviii cm tall 3. 9 cm tall 4. 4. 5 cm tall v. 3 cm tall
A 34. 5 A sparse lens has focal length f = – 12 cm. If an object 9 cm tall is placed 24 cm from the lens, what is the height of the image? one. 27 cm tall 2. 18 cm tall three. ix cm alpine 4. four. 5 cm tall 5. 3 cm tall
Q 34. vi Which statement is truthful virtually a farsighted (hyperopic) eye? 1. the image point is in forepart of the retina; a converging eyeglass lens is used to correct this status 2. the image betoken is in forepart of the retina; a diverging eyeglass lens is used to correct this condition 3. the paradigm bespeak is behind the retina; a converging eyeglass lens is used to right this condition 4. the paradigm bespeak is backside the retina; a diverging eyeglass lens is used to correct this condition
A 34. 6 Which statement is true about a farsighted (hyperopic) eye? one. the image indicate is in front of the retina; a converging eyeglass lens is used to right this condition two. the image point is in front of the retina; a diverging eyeglass lens is used to correct this condition 3. the image indicate is behind the retina; a converging eyeglass lens is used to correct this condition 4. the prototype indicate is backside the retina; a diverging eyeglass lens is used to correct this condition
Q 34. vii You are choosing lenses for a telescope that you lot will use to look at the Moon and planets. You should select i. an objective lens with a long focal length and an eyepiece lens with an even longer focal length 2. an objective lens with a long focal length and an eyepiece lens with a shorter focal length 3. an objective lens with a brusque focal length and an eyepiece lens with a longer focal length 4. an objective lens with a short focal length and an eyepiece lens with an even shorter focal length
A 34. 7 You lot are choosing lenses for a telescope that you will use to wait at the Moon and planets. You should select 1. an objective lens with a long focal length and an eyepiece lens with an even longer focal length two. an objective lens with a long focal length and an eyepiece lens with a shorter focal length 3. an objective lens with a brusk focal length and an eyepiece lens with a longer focal length 4. an objective lens with a short focal length and an eyepiece lens with an even shorter focal length
Q 34. viii You are designing a telescope that will apply a unmarried lens. The purpose of the telescope is to accept photographs of the Moon. The linear magnification m of the epitome will exist in the range 1. grand > ane 2. 0 < thousand < ane 3. – 1 < m < 0 four. grand < – 1
A 34. eight You are designing a telescope that volition utilize a single lens. The purpose of the telescope is to accept photographs of the Moon. The linear magnification yard of the image volition exist in the range 1. chiliad > 1 2. 0 < thou < 1 three. – 1 < 1000 < 0 4. g < – 1
