The eye of the Atlantic giant squid has a diameter of 3.50 × 10^2 mm. If the eyeis viewed in a concave mirror with a radius of curvature equal to the diameter
of the eye and the eye is 0.800 × 10^3 mm from the mirror, how far is the image
from the mirror? What is the size of the image? Is the image real or virtual?
Answers
Answer:
q = 224 mm, h ’= - 98 mm, real imagen
Explanation:
For this exercise let's use the constructor equation
where f is the focal length, p and q are the distance to the object and the image respectively.
In a mirror the focal length is
f = R / 2
indicate us radius of curvature is equal to the diameter of the eye
R = 3,50 10² mm
f = 3.50 10² /2 = 1.75 10² mm
they also say that the distance to the object is p = 0.800 10³ mm
1 / q = 1 / f - 1 / p
1 / q = 1 / 175 - 1 /800
1 / q = 0.004464
q = 224 mm
to calculate the size let's use the magnification ratio
m =
h '=
h ’= - 224 350 / 800
h ’= - 98 mm
in concave mirrors the image is real.

Explanation:
Theory is the set of knowledge that seeks to explain, with a high degree of accuracy, all-encompassing phenomena of nature, that is, it is different from the meaning of the word "theory" used in everyday life, when we say that something "is only a theory "in the sense that it is a mere speculation.

B. Compressions and rarefactions occur throughout a transverse wave.
C. The wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
D. Amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the
maximum distance the molecule has moved from its normal position.
Answers
Before coming into conclusion first we have to understand the nature of longitudinal wave and transverse wave.
The longitudinal wave is a type of mechanical wave in which the direction of wave propagation is parallel to the particle vibration.In such type of wave one will notice compressions and rarefactions.
Compressions are the high pressure zones where the particles are very close to each other and rarefactions are the low pressure regions where there is large separation between particles. Hence a longitudinal wave is a series of compresions and rarefactions.
The wavelength of a longitudinal wave is the distance between two successive compressions or rarefactions. Hence the wavelength is measured parallel to the direction of wave. As the particle vibration is parallel to wave propagation ,so the amplitude of the wave is measured parallel to wave direction.
Transverse wave is such type of mechanical wave in which the particle vibration is perpendicular to wave propagation.Here crests and troughs are formed.
The distance between two successive crests or troughs are called wavelength which is measured parallel to the wave propagation. As the particle vibration is perpendicular to wave propagation,so the amplitude of the wave is measured perpendicular to the wave propagation.It is so because amplitude of the wave is the maximum distance travelled by the particle from equilibrium position.
Out of the four options given in the question only the option 3 is correct .Other options are wrong as violate the nature of longitudinal and transverse waves.
Answer:
C. The wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

At certain altitude, the temperature of air decrease, The air becomes saturated and water vapour molecules starts condensing.
As the altitude of air increase, the atmospheric pressure decrease due to which the temperature of the air decrease. The water molecules in the atmosphere start condensing, which saturate the air (that is air can no hold water molecules), due to which the water vapour molecules starts condensing and falls on the earth in the form of rain.
