Answer:
P = -1.67 dP
Explanation:
given,
myopic lawyer has a far point of = 60.0 cm = 0.6 m
If a person is suffering from myopia then he cannot see the farthest object clearly.
Image of far object does not form on the retina so, the image appear to be blur.
using lens formula
P = -1.67 dP
Answer:
Explanation:
From the question we are told that:
Mass 
Initial heat of pan 
Final heat of pan 
Generally the equation for Heat energy released is mathematically given by
The correct option is 0.5 M
Calculation
Wavelength is defined as the ratio of velocity of a wave to its frequency. It is measure in meters. Mathematically, wavelength is given by the following formula:
Wavelength = wave velocity / frequency
From the details given in the question,
Wavelength =?
Velocity = 340 m/s
Frequency = 680 HZ
Wavelength = 340 /680 = 0.5
Therefore, wavelength = 0.5 M
Answer:
The answer is (d) is totally reflected
Explanation:
Using the total internal reflection concept.
This concept state that:
"If the angle of incidence is greater than the critical angle then the light will not refract but it will reflect back totally"
Using the above statement, as incident angle is 42 degree and critical angle is 41 degree it means incident angle is greater than the critical angle. Therefore, light will not refract but it will totally reflected.
C. the distance from earth earth to the sun
