Longer wavelengths (and lower frequencies) have less energy. Shorter wavelengths (and higher frequencies) have more energy.
Gravitational potential energy depends on the difference of height. If the length of the ramp is changed, but the endpoints have the same difference in height, there won't be any change in gravitational potential energy. If, on the other hand, the change is done in a way that the height does change, then gravitational potential energy will also change.
Yes , because when lens is deeped in water its R.I changes & hence focal length is increased
If everything is working as it should, the image distance in the eye never changes. The image always needs to focus on the retina, which doesn't move. This is where the lens comes in, specifically its ability to change its focal length. When the object distance changes, the focal length has to change, in order to keep the image distance constant. Muscles around the lens change the shape of the lens, in order to change its focal length.
The pitch of the ruler changes because of the vibration.When there is more space for the ruler to vibrate and make a sound,the pitch changes and becomes softer and longer.When there is lesser space for the vibration, the sound is shorter and louder.
Because - the angle of the lamp in relation to your body changes,
No, the length of the muscle fibers does not change. In isotonic movements is when the length changes.
If we condier the wave in the form of photons, then as wavelength increases then energy content of each photon decreases.
When length gets longer the area will be larger. As the length gets shorter the area will be smaller.

The length of day and night
No. It changes every day.
It will Lengthen and shorten during the day, as the angle of the sun changes
Nothing can change the length of day and night except the normal seasonal progression.
Volume= Length * Breadth * Height so if any of the variables change then volume will change.
Its length, linear density, thickness, and temperature all change.
Yes , because when lens is deeped in water its R.I changes & hence focal length is increased
Temperature changes and vibrations can cause strings to change in length or tuning pegs to move.
