a 0.3kg is attached to spring and oscillates at 2 hz with q of 60 find spring constant and damping constant

While outside watching the projection of the eclipse with their very nice pinhole projector, the students noticed images of the eclipse on the ground under the tree nearby The images were not only larger than their pinhole projection, but there were many images of the sun to see all at once.
One student took out a ruler and measured the image of the sun on the ground to have a diameter of 6 cm. Approximately how tall was the tree? Enter your answer in meters.

2. An object 15cm high is 30cm from a pinhole camera. If the height of the image formed at the back of the camera is 10cm, calculate the image distance

Describe how you would use Newton rings to determine the wavelength of a monochromatic radiation and refractive index of the medium and derive the relvent formula .

With an increase in the thickness of the soft tissue by 4cm, the intensity of the x ray beam passing through the tissue decreased 9 times. Calculate the linear tissue absorption rate

An object is placed 1)10cm 2)4cm from a concave mirror of radius curvature 12cm. Calculate the image position in each case and the respective magnification

.In Young’s double-slit experiment the distance between the two slits is 0.8mm and the distance of the screen from the slits is 1.5m. Calculate the width of the bright band when the slits are illuminated by a monochromatic light of wavelength of 5560×10-10m.

Determine the angle of deviation of a ray by a glass prism with a prism angle of 3° if the angle of incidence of the ray on the front face of the prism is zero. The refractive index of the glass material is 1.5.

A ray of light is refracted through a prism of angle 70°. If the angle of refraction in the glass at the first face is 28°, what is the angle of incidence in the glass at the second face?
